Somebody from the ravelrysite asked me, how i atttached my freeform pieces. I made it visual by means of photos.
This is a yet unused scrumble. You can clearly see, it's build up form 5 leave-shapes, then crocheted together.
You just slipstitch from one border of the leave (in this case) to the other. Sometimes, with different shapes, the borderstitches don't match, so you have to cheat a little and make iwo in one borderstitch to make it fit. Just as long as the work stays flat. In this scrumble i crocheted a couple of rounds double crochet at the bottom. The embellishment in the centre of the leaves also is done with slipstitches.
