My youngest, has a good friend who is a competitive gymnast. For her birthday gift, Megan really wanted to make her a "grip bag". I knew what the wrist grips were, but my daughter's skills at describing a grip bag left a lot to my imagination. I couldn't figure out why you'd need a specialized bag and how I could sew one. Finally I looked it up. All it is, is an aprox. 9x11" bag with a drawstring. Okey-dokey. I could sew that.
I loved the fabric Megan picked for the inside, though I really wanted it on the outside since it matched the fabrics she picked for the backpack. I did sneak it into the design of the water bottle holder. I simply used the scraps from trimming the fat quarters down to size. They were perfect. Originally, I thought the pocket was going on the outside, so I put the solid grey on the edge, to set it apart from the zig zag pattern.
I hope it gets lots of use!
