I made a small 'purse' using the metal tape measure for closure. [Actually have made quite a few of t hem because I love them.] I put my yo-yo stuff in this one, which included material, the Clover yo-yo maker, thread, needle & threaders, and cheap small scissors. I take this to my quilt guild meetings and such as well. I have a larger 'purse' that holds my circle maker and extra fabric; it is kept with an old small rotary mat, so I can keep up with the demand.
I love it because it is softsided and will enlarge itself only as needed, yet is compact.
The funny part is: I can get 4 yo-yos done in an hour, almost. My hands just won't do it any faster. Last quilt guild the [newer to me] tremors were so bad that another quilter sitting next to me threaded my needle when he saw I was shaking so much. Aren't quilters great!
