Painted Flowers by Shakespeare's Peddler
Stitch count is 235 by 80. Stitched on 40 count Black Swan by Fox & Rabbit (Chalkboard by Xjude would also work really well!) The second picture shows you what it might look like on a lighter fabric of your choice (if you don't like stitching on dark!)
Threads are DMC floss, Weeks Dye Works Cornsilk, and Sampler Threads Weathered Barn.
This is also available as a PDF/download, which is sold separately on my site.
