Here's my TAST sample for Lace Border stitch. I started on the left hand side and managed to work a variation before I mastered the actual stitch! I'd noticed some others had had a few problems with the stitch but they all seemed to have managed it so I put my sample aside for a couple of days then went back to it and finally worked out how it was meant to be done. But I like my variation as well so left it there. The middle section on the right was also very attractive, so another useful stitch.
