I'm still working on triangles.
All the centers are made the same, a tatted circle motif that is then stitched to the inside of the triangle with bare thread. Attaching the centers this way is a bit tedious. The triangle has to be pinned down to a board so they don't get pulled out of shape too badly while putting the centers in. And while stitching them in the thread has a tendency to catch on the pins holding the triangles. It did seem to get a bit easier as I went along and got the hang of it.
Even pinning the outsides while adding the centers deformed the triangle shape. Once the centers were attached each one had to be blocked to have them lie flat. After pinning then out flat they were sprayed with water then left to dry that way, which worked out well. The whole thing was blocked and dampened again after joining the triangles together, too. It now lies flat very nicely.
This arrangement was suggested by muskaan
in a comment made on my first triangle post a few weeks ago. I looked at the first triangle and could see something like that, so I tried it. I'm now trying to decide if/what I want to do in the center. Maybe something around the outside as well. In white? White and red?
Hmmm, I'll have to work on that.
