Another one out of the UFO drawer and ready for use -
A few years ago we were making a mesh food cover at our sewing club. We used the Double Mitre Ruler by the Sewing Revolution to make the frame, then a mesh fabric sewn into the frame. The corners were to be weighted, but as I have not found the pattern, I am not sure how that was done. I decided not to try weighting them at this stage, and can do so if needed at a later time.
I did the frame in the class, so just had to sew the mesh in at home.
