First, a line drawing of a small cluster on paper. I painted splodges of silk paint on dampened calico in roughly the right places.
Then traced the drawing onto light interlining and pinned it to the back with wadding sandwiched between it and the painted fabric.
Stitched the outlines from the back - and I DID have the drawing the right way round! (Think about it!). Then some more stitching on the front.
This is how it ended up on the back. I almost prefer it to the front. Funny how that often happens, the bit you are not trying for turns out better! This then got covered by a backing unfortunately because I didn't manage to work out when the backing should be added and couldn't really leave the interlining as the backing. Next time!
