Here's my TAST sample for Thorn stitch. The year and the challenge are nearly over but Sharon has proposed a new challenge for next year called Take it Further - click on the link to read all the details.
I'd like to give it a go but not sure I'll manage to meet the deadlines. Although TAST was weekly and therefore sounds like more work, the samples could be done very quickly if so minded and didn't need any pre-planning. Developing a design is very slow work for me so I'll just have to see how far I get.
