If you have an old dress laying around and want to reuse it here is a fun idea!
Step 1: Find an Old Dress
If you have an old dress (preferably with frilly Sleves then you are on your way!
Step 3: Hemming
most likely the section you cut will need to be hemmed on one side so decide how large you want it ( for kitten I am doing 1 1/2") and hemm the side you cut.
Step 4: Sewing Into a Circle
Next you need to sew together the bottom side( the smaller inner part that will go on the back of the head) it is ok if ther is a hole here a lot of bonnets are made with holes in the back. If hand stitching I would double thread and cross stitch to make sure it's strong. Make sure to hemm on the inside
Step 5: Attaching Ribbon
Next you need to sew on the ribbon (or peice of hemming off the dress as I did) to the bonnet so you can secure it on. You want to attach them on the inside of the bonnet to the hemming as shown.
