I found this triangular medallion here. For some reason I can't find the picture anymore.
I tried to make the rings in the centre as even as possible. I still have trouble with "how firm do I pull the thread through the double stitches". I suppose it is like knitting and crochet, in the long term you get a steady hand.
The thread is DMC perlé 12.
This is a pattern by Mark Myers. Here is the link.
It is supposed to look like a hat. With flowers on it (as in the pattern), it is a perfect hat for Ascot ;)
I liked the shape and I had to try it. The thread I used is: DMC perlé 8
Here and there it is a bit wobbly, I keep practising.
Both shapes will probably find a place on the Crazy Violets quilt.
When they are sewn on, they will look OK.
