As you can see they are as easy as can be!
I used fabric I already had and cut away. I used white thread with a 3/8 seam and plain old straight Velcro that I cut off from a roll. The instruction on the pattern say to sew them right sides together and turn them right side out. You could do that for sure, I personally like it with the rough edges look. I think that is about all, they are pretty self explanatory!
And the beautiful thing is the more you wash them the cuter they get!
