Okay, I'm not sure whether to term this a failed experiment or not. I like the heart, but hate the embroidery - (Heart) On My Sleeve -- of course the cuff took 20 mins and the stupid lettering half the day.
I was reading through an old crochet stitch book - Adventures in Crocheting by Barbara Ayers, 1972 - that I found at an estate sale and saw an example of popcorn stitch used to make a Christmas tree motif in green against a field of white single crochet. It took me a few tries to get the heart right -- and I did stitch around the outside of make sure it kept its shape.
The stitch I used isn't exactly popcorn - it was called a hazelnut stitch in this book - kind of a DC done 5 times in the same stitch, keeping the last loop of each stitch on the hook until you pull through all the loops on the 6th pass.
Maybe if I make a wider cuff so the embroidery has more room - or make multiple hearts and hold off on the messages until I'm more skilled. At any rate, I like the idea of the 3-D designs and am experimenting now making soft-studs with gray/silver yarn on a black single-crochet cuff.
Anyone have any tips for embroidering on crochet?
