Sleeping bag liners are a handy way to keep your sleeping bag clean and improve its longevity. They are also useful for adding an extra layer of warmth in cold weather and can be used on their own in hot weather. Liners come in two main types: mummy-shaped and rectangular. Rectangular liners, also known as travel sheets, can be used independently or inside a rectangular sleeping bag, while mummy-shaped liners are designed to slip inside any shaped sleeping bag. In terms of materials, liners can be made from synthetic fabrics, which are moisture-wicking and breathable, or insulated fabrics, which add warmth. Liners can also offer bug protection. When it comes to attaching a double sleeping bag liner, options include sewing a queen-sized sheet together with a zipper or using Velcro fasteners to keep the sides together.

Sewing a liner
First, gather your materials. You will need a sleeping bag, a sheet of fabric, a pillowcase, sewing thread, scissors, and a needle. You can use a sewing machine or serger, but this project can also be done by hand. If you want to attach your liner to your sleeping bag, you will also need about eight to ten tab snaps (inch-long pieces of fabric with snaps on the ends) or a yard or two of ribbon.
Next, prepare your fabric. Fold your sheet of fabric in half lengthwise, with the selvage edges at the top and bottom. The selvage is the term for the white edges with the printed fabric information on it. The length of your liner will be the fabric distance from selvage edge to selvage edge. You may need to trim off any excess fabric or add additional fabric to ensure that your liner is long enough to fit your sleeping bag.
Now, it's time to sew the pieces together. Pin the pieces together before sewing to prevent any seams from puckering. Sew the pieces together using a small zig-zag stitch to join the seams. Trim off any excess seam allowance, and consider using a satin stitch to add durability and prevent stitches from ripping.
After your pieces are sewn together, it's time to add any additional features, such as a pillowcase or zipper. If you are adding a pillowcase, sew it to the top of the flat sheet, lining up the opening of the pillowcase with one of the sides of the sheets. You can also create a pillow pocket by drawing a rectangle on one side of the fabric that is the same width as the top of your sleeping bag and extends about 20 inches above the hood. Fold the fabric over to create a pillow and sew along the bottom and one vertical side to create a pocket that can be stuffed with a fleece or puffy jacket.
Finally, attach your liner to your sleeping bag. Place your liner inside your sleeping bag and mark where the snaps or ribbons will go. Sew the attachments to the inside of your bag, and hem the top side of the liner to ensure it does not extend above your chin when you are inside the bag.
Your double sleeping bag liner is now complete! Enjoy your cosy and comfortable sleeping setup.

Using velcro
Prepare the Materials
Firstly, gather your materials. You will need a suitable sleeping bag liner fabric, such as polycotton or a thin material, and velcro strips or dots. You can find these materials at outdoor gear stores or fabric suppliers.
Measure and Cut
Measure the length and width of your sleeping bag where you want the liner to be attached. Cut the liner fabric to size, adding a few extra inches on each side for a comfortable fit. If you're using a queen-sized sheet, as some people prefer, you may need to adjust the size accordingly.
Attach the Velcro
Attach the velcro pieces to the sleeping bag and liner. Place the velcro strategically along the edges of the liner fabric, spacing them evenly. The soft side of the velcro should be attached to the liner fabric, while the rough side should be attached to the sleeping bag. This ensures a secure hold when the two sides are pressed together.
Secure the Liner
With the velcro in place, carefully align the liner with the inside of your sleeping bag. Press the velcro pieces together to secure the liner in place. Check that the liner is attached securely and adjust as needed.
Benefits of Using Velcro
By following these steps, you can efficiently attach a double sleeping bag liner using velcro, enhancing the warmth, comfort, and cleanliness of your sleeping bag setup.

Zipping together
Zipping two single sleeping bag liners together is a great way to create a double sleeping bag liner. This can be done by purchasing two single liners and modifying them to join together. This can be done by taking them to a tailor or seamstress, or by sewing them together yourself.
Some sleeping bag liners come with zippers on the sides, which can be useful for joining two liners together. If you are creating your own liner, you can add zippers to the sides of your chosen material. This will allow you to zip two liners together to form a double.
It is also possible to buy ready-made double sleeping bag liners, which are designed to work with specific brands that have joinable sleeping bags. However, not all brands offer this option, so it may be necessary to modify single liners to create a double.
When creating a double sleeping bag liner, it is important to consider the material you will be using. Polycotton or polyester are good options, and you may want to order the fabric in advance if you prefer a thinner material than bedsheets. It is also worth considering the size of the liner, as you may want to opt for a larger size to accommodate two people comfortably.
By following these steps and considering your material and size options, you can successfully create a double sleeping bag liner by zipping two single liners together.

Choosing a material
The material you choose for your double sleeping bag liner will depend on your intended use. Here are some factors to consider when choosing a material:
Warmth
If you are looking for a liner that will add warmth to your sleeping bag, consider a heavier material like fleece. Fleece liners can add a significant amount of warmth to your sleeping bag, especially in cold temperatures. They are also ideal if you are a restless sleeper as they offer some stretch. However, fleece liners can be too warm for some people, causing them to overheat.
On the other hand, if you are looking for a lightweight liner that provides a little extra warmth, silk is a good option. Silk liners are ideal for most hikes as they are lightweight and provide a small amount of extra warmth. They are also easy to clean and dry quickly.
Cotton liners fall between silk and fleece in terms of weight and warmth. They are ideal for travel and hostel-hopping as they are easy to clean and dry, but they offer no warmth when wet, making them less suitable for backpacking or hiking.
Synthetic materials like CoolMax® are also an option, offering moisture-wicking and breathability, making them suitable for humid conditions.
Ease of Cleaning
If you plan to use your liner frequently and want to be able to clean it regularly, choose a material that is easy to clean and quick to dry. Silk, polyester, and cotton liners can be machine washed and dried, making them convenient for travellers who may not have access to laundry facilities.
On the other hand, materials like merino wool require hand washing, which may be less convenient when travelling.
Durability
Consider the durability of the liner material, especially if you plan to use it frequently or in harsh conditions. Some materials, like polyester, are known for their durability, while others may be more prone to wear and tear.
Bug Protection
If you plan to use your liner in bug-infested areas, consider a liner with built-in bug protection. Several models offer Insect Shield® protection, which can help keep bugs at bay.
Size and Weight
If you are backpacking or hiking, size and weight become important considerations. Silk and synthetic liners are ultralight options that can add warmth without weighing down your pack. Cotton and polyester liners are also relatively lightweight, while fleece liners can add a significant amount of weight.
Additionally, consider the size of the liner in terms of its dimensions. If you are tall, look for a long liner, and if you need extra width, choose an extra-wide liner.
In summary, the key factors to consider when choosing a material for your double sleeping bag liner are warmth, ease of cleaning, durability, bug protection, and size and weight. Choose a material that best suits your intended use and personal preferences to ensure a comfortable and practical night's sleep.

Adding a pillowcase
Materials and Preparation:
Before you begin, gather your materials. You will need a double sleeping bag liner, a pillowcase, a needle and thread or a sewing machine, and any additional tools you may prefer for sewing, such as pins or fabric markers. It is recommended to use a twin-sized flat sheet for your liner, as it is the perfect size for most individuals. You can also use a queen-sized sheet and adjust it to the desired length.
Sewing the Pillowcase:
Start by lining up the opening of the pillowcase with one of the sides of your flat sheet liner. Place the pillowcase at the top of the sheet, where your head would typically rest. You can use pins to secure the pillowcase in place along the edge of the sheet.
Next, begin sewing from the inside of the pillowcase, along the edge where it meets the top of the sheet. Sew towards the end of the sheet, ensuring that the pillowcase is securely attached. You can use a simple running stitch or a sewing machine for this step, depending on your preference and the tools available.
Finishing Touches:
Once you've sewn the pillowcase in place, you can add any additional features you desire. Some people like to add Velcro fasteners along the sides of the liner to keep it snug and secure inside the sleeping bag. You could also consider adding a zipper to one side of the liner, making it easier to get in and out.
Care and Maintenance:
Remember that one of the benefits of a sleeping bag liner is its ease of care. Your new pillowcase addition will also share this advantage. When it's time to clean your liner, simply remove it from your sleeping bag and toss it into the washing machine. This will help keep your sleeping environment hygienic and comfortable.
Now you're all set! With your custom double sleeping bag liner and attached pillowcase, you can look forward to cosy and convenient nights, whether you're camping, backpacking, or simply enjoying a night in your own bed.
