Cobalt Blue Round Robin

This is an update on my work on Skye's block for the cobalt blue group of the blue round robin at CQ4Newbies. I was inspired by Ing's work to try a butterfly in silk ribbon embroidery. For this round robin we are to stick almost entirely to blue embellishments. I began with some feather stitching to which I added beads, spankles and straight stitched ribbon. Then I outlined the shape with a running stitch in floss. I began on the upper wings to fill in with a looped wild rose, then spider roses and some folded roses made with wired ribbon and stitched on with floss. Between the larger roses I filled in with rose buds, folded and stitched: gathered bits, and french knots. The lower wings are covered in ribbon using the plume stitch and french knots. It is still not complete but I could not wait to post a photo. Oh! yes, I wanted you to know the block is 12 inches square and my motif is about 4 by 6. Do you put length or width first??
