|Grime guards for 11", 8", and 6"|
this post from the Thread-Bare blog. Commercially, they're between $9 and $12 each. With this reclaimed fabric and a couple of packages of 1/4" elastic, I have a complete set for a couple of dollars.
The fabric wraps around the project mounted on the Q-Snap frame. Excess fabric can be tucked in to keep things neat and out of the way for stitching.
This is the back of a project.
I have LOTS more fabric to make more sets. I just need to get some more elastic.
