Orna Willis

Orna Willis is known for colorful charted designs that are chockfull of a variety of stitches but she has stuck a toe into the painted canvas waters with a series of three bird canvases.  The first canvas, the quail, has a stitch guide for $20 extra.

The oriole and the pheasant canvases can be seen here.  They don't have a stitch guide yet.

I've not seen any of Orna's books or charts in person but her free designs on her website are well described with great diagrams.
