Canvaswork . . .

I finished the canvaswork piece we started at West Country Embroiderers this month. Except that it needs some more beads and sequins. And I have to decide what to do with it! As usual. I really enjoyed doing it, and want to do some more.
This is my practice piece. Having only tried canvaswork once before, a small and unsuccesful attempt, I thought I'd try a few threads and see what worked best. I had bought single canvas with a larger mesh (eyesight) and wanted to see before the workshop day which ones would cover it enough. We did paint the canvas first, so bits showing were not a problem. I guess with white canvas you would want to cover it all up? I thought it needed the thicker threads - stranded cotton, soft cotton, some wools, thicker perlé, those knitted ribbon things or else finer ones used double. Our tutor used some torn chiffon strips but I didn't get round to trying that.
