I have been making my own heat packs for years. It is very simple and you can make one for very little money. They take about 15 minutes to make. You need the following items:
• Piece of material – I only use cotton material. It can be whatever size you desire. For this project, I chose a pre-cut single fabric square that I picked up at Walmart for $0.99. This one measures 18 x 21.
• Flaxseed – I prefer flaxseed because it heats up nicer and it has a wonderful, smooth feel to it. I know a lot of people use rice but it can burn and has a rougher texture. For this project I used 30oz of flaxseed. I bought two 15oz bags of flaxseed from Aldi’s for $2.19/bag.
• Essential Oil – This is optional. I like my packs to have a scent. For this project I used one of my favorite scents, DoTerra’s Serenity. How many drops is up to you and will depend on how strong your oil is. I used 3 drops for this pack but I probably could have only used 1 or 2 drops because it is so concentrated. Another method is to not add any oil during the construction of the bag. Instead, add the oil to the outside of the bag before each use. Do this after you’ve heated up the bag. This allows you to change the scent to suit your mood.
1) Spread out your material and fold it in half. Cut it into the size and shape you want your pack to be. Make sure you have the inside facing out when you start sewing.
2) Sew three sides of the material, leaving the top open.
3) Turn the material inside out.
4) Mix a few drops of your essential oil with the flaxseed (optional).
5) Fill the material bag ½ to ¾ full of the flaxseed. This is your preference. I fill it about ¾ full.
6) Sew the end of the bag together and your bag is finished.
You can make any size or shape you want. I made a simple rectangle for this project so it would be easy to follow. Your options are pretty much endless. This is a good size pack. I usually heat it in the microwave for 3 – 4 minutes. However, every microwave is different. The first time you heat it up, I would recommend starting at 1 minute and then add on in 1 minute increments until you reach your desired temperature.
