I recently made a pincushion/threadcatcher that sits beside the sewing machine and is most handy but sort of stationary due to the weight. I wanted something I could move around to wherever I’m working. Last summer a friend gave me this jar that we both thought looked a bit like a mushroom base. Extra bonus, it’s exactly the right size for my special button collection.
Inside the lid is a cut out from a card that came in a swap, I think this one was from you @Reinikka?
If you’d like to make something similar, I cut a circle 2" larger than the jar lid.
Then used a dress makering trick, sewing 3 close together rows of stitches right next to the edge of the fabric with the stitch tension set very low. Knot all the threads on one side.
Carefully pull the loose threads in a bunch and evenly distribute the gathers. Knot when the correct size, trim the thread ends.
I glued a piece of cardboard on the lid ring, stuffed with fiber fill, and used E-6000 glue to attach the gathered edge of the fabric to the lid ring, held in place with clothes pins and a wide rubber band.
Once dry, I trimmed the edge and glued on a strip of lace with a button sewn on.
