This is how i lay the motifs out, to get a balance between them. It's not always the way it turns out:) First I crochet a border of ch 3, 1 dc around the larger motifs to get an more open view. After i'm done, i crochet the leaves (in this case) straight onto the motifs and build it from there.
This is the result... I still need some 'filler' leaves to get the full size.
