I made these Toiletry bags for most of the men in our family since they all needed them, and this was a gift that actually was homemade as well as liked and used.
Step by Step Instructions
Square up your fabric to the correct size I made mine 14×21
Place the zipper and pin or binder clip it in place and sew one portion of it and sew it into place
Then top stitch that portion too.
Trim the edges so everything looks nice, turn right side out and enjoy!
