Magnetic clamp way of sewing masks - brought out of retirement
The clamp. Magnets. Steel. Glue. Polypropylene placemat from the supermarket (£1 at the mo, was £3.50 before a sale). Rubber baker's sheet (glued) that was added after a lot of a use for the working clamp, and me thinking I could probably improve it all. Not sure that it does - unnecessary additional thickness under the presser foot of the sewing machine, for little benefit.
Sheets cut up:
Sheets in the clamp:
The first sew is from the bottom left, clockwise round to the bottom right, but NOT across the bottom.
Then the clamp is set aside. Cut excess off, and turn inside out. There's more steps of course.
