First, you need to choose a fleece fabric of your preferred color or pattern. I recommend you get 2 sets of the fabric measuring up to 1 yard.
Next, you should cut your fabric to determine the size of your pillow. I cut mine so that the pillow would be 16inx16in but cut at 22 inches so I had room for 3 inch slits.
After modifying your fabric size, it's time to cut the slits. I made mine 3 inches long and 1.5 inches wide, and used a post it note for accuracy.
Cut the slits into all 4 sides of the fabric.
Cut the unwanted corners out.
Tie the bottom and top slits together, and then double knot it and stretch it. Leave one side open for stuffing!
Get some stuffing from your local craft store. I recommend a larger size.
Stuff your pillow. Don't forget the bottom corners! Then, finish tying your last set of slits and stretch them out.
This is optional. You can press into the pillow and spread around the stuffing to ensure that it's balanced throughout the entire pillow.
Your pillow is finished! :)
