Cynthia Thomas writes a great many stitch guides for Melissa Shirley designs. Search on Melissa Shirley to read about them here in an earlier article. There is a link about a new stitch guide series for cute old fashioned Halloween pails from EyeCandy Needleart here.
Melissa Shirley's website has a profile for Cynthia.
Cynthia has stitched the seasonal tree ornament set by Rebecca Wood. A slide show on the Rebecca Wood home page shows these off beautifully! (I don't know if this is still available as this profile was written in 2011 and websites change.)
By the way, Cynthia has a blog You can follow the adventures of The Hill Country Stitcher here but Cynthia's not maintaining the blog any more. Still, it's a good place to see some her older models.
Her first book is out, too. You can get a glimpse of the techniques covered in Noses, Roses and other Fun Stuff here.
UPDATE: Cynthia is starting to post photos of all her stitch guide models on her Facebook page. It will take a while for her to post all her guides as she is asking the designers for permission to use their photos, but you can always message Cynthia and ask if she has a guide for the canvas you are interested in.
