Stitch By Stitch in Larchmont has added a great new stitch guide for a mermaid tooth fairy pillow to their collection. I am not certain who the designer of this canvas is but it might be Gayla Elliott. Anyone know?
Ruth Schmuff is also doing a stitch guide for mermaids, this time for four Sandra Gilmore (Once in a Blue Moon) mermaid panels. These were originally released for a tuffet but Ruth talked Sandra into doing rectangular versions. Then Ruth wrote stitch guides for all four mermaids.
Whatever style mermaid suits you, there is a stitch guide!
UPDATE: EyeCandy's mermaid pirate also has a Ruth Schmuff stitch guide. Ada (the genius behind EyeCandy) posted a photo of a finished mermaid with her pirate patch and octopus but Ruth's stitch guide is slightly different as you can see from the photos of all the supplies.
