Yes this design screamed vinyl. I bought some in the remnant bin a while back, but have never used it. What size needle did you use?
Have you found a clear vinyl that doesn't tear away from the stitches in the washer? I don't have any luck getting vinyl to "stay".
This one was pretty thick....I think the trick is to digitize the satin stitch with the stitch holes spread out wider than normal...
Well now, this is how cats scare fish! The eyes really give this design a great interpretation of how each animal feels. Nice work!
