To embroider this butterfly I used DMC floss cotton 939, 3840 and 517.
The stem is embroidered with stem stitch and the leaves with fly stitch worked close together, all with 2 threads.
The flower consists of the embroidered triangular part made with straight stitches 1 thread, 3 double lazydaisy stitches 2 threads and a cast-on stitch also made with 2 threads.
The colors used are DMC floss cotton 746 and 934 and House of Embroidery stranded cotton Daffodil 47.
