My notes = doubleknit version. (That’s how I did this one, just for dblk practice. Needle should be smaller, especially for DK’ing. Can see stuffing.

2nd heart = MC/O 14/side, GSR 1st 7 sts (2 GSR per edge), work across twice, repeat with 2nd 7 stars. Work all sts (in rnd) - 2 plain rounds, then decrs by 4 every alt row (stuff at a convenient point) till 8 tot. sts. Graft.
