When I wrote my earlier post today I knew there was another tip I had heard today but I simply couldn’t think of it! However, I have remembered it now!
To keep crewel work or other hand embroidery clean whilst stitching:
When doing crewel work or other hand embroidery in a hoop, place the outer ring of the hoop on a flat surface, tear a strip of cling film large enough to hang over the edge of the hoop, all the way round. Place the cling film on the outer ring of the hoop, then place your piece of work with the right side facing down on the cling film, making sure that the area you want to work on is within the circle of the hoop. Push the inner hoop down onto the fabric and secure it in place. Turn the hoop over so that the right side of your work is uppermost. With scissors, carefully score the cling film, encircling the area you are about to stitch. Remove the piece of cling film and begin stitching. The cling film protects the area of fabric that is not being worked upon.
