Well definitely the last insertion stitching on the agenda . This has been a fun exercise but I have run out of options that fit in with TAST for the moment.
This one is Plaited Insertion - each stitch is not cretan but enough of them are for me to include it in my TAST. Mary Thomas says to leave at least 3/4 inch between the hems and use a firm thick thread. I did leave the 3/4 " but am not sure what would happen if I unpicked the tacking - a really floppy join, I imagine. The insertions are all still on the A4 paper to make it easier to store together in a folder. (My folder Hems and Edges has grown nicely in the last couple of weeks.)
The thread is a painted cotton weaving yarn and somewhere between a#8 and #5 perle cotton in size. Aida was the fabric.
