They are quick and easy. You need scrapbooking paper (the heavier double sided card stock will work best), #3 crochet thread, hole punch (I used a small size, but bigger would work too) and a small crochet hook (mine was a metal size C). Cut out your shape, punch holes evenly around the edge...leaving a bit of width from the edge, crochet around the edge with a repeat of sc, ch 1 (you may want to ch 2 or even 3 depending on how far apart your holes are). If you don't have enough chains between the holes, your project will pull and curl. Complete round 1 with a sl st into the first sc. Rnd 2 can be whatever makes you happy! I placed (1 sc, 1 dc, 1 sc, 1 sl st) into each ch 1 space. If you put more chains between the holes, your space will be ch 2 or ch 3 space into which you work that repeat. Truth be told, some of my spaces are ch1, some are ch 2...there are no rules...just whatever keeps it looking pretty! A shell pattern around the edge would be cute too!
Of note, when working round 1, do whatever looks good at the top center of the heart...I don't think I chained in between those three sc stitches up there because they sit so close to one another. At the bottom center, i worked three different sc into one hole, separated by ch 1.
They're fun and can be strung together for garland, slipped into a lunch bag or left on someone's desk as a surprise (write a note in the middle if your handwriting/cursive are better than mine) or write it on the rear side. With two sided stock, these are pretty from either side!
