Here's the tool the magazine picture and my completed poppy.
and followed the pattern instructions except I did only 4 rows per petal and made 4 petals, but decided to use only 3. I also omitted the beads.
I made 3 red petals : ch2, then work 1 dc, 1 HTR, 2 Tr and 4 DTR, then 2 TR, 1 HTR and 1 dc into the second chain. pull to close hole and fasten off. Make 3 like that.
I think I chained about 14 or so. dc in 3rd ch, then 1 Htr, 1Tr twice per ch, 1Dtr twice per ch, 1 Tr twice, 1 Htr, 1 dc and ss the remaining ch. sew ends into leaf securely.
Sew the ends in securely, saving one for the brooch back. Sew the button on with black thread.
Sew the brooch back on with the last red end and finish off. VOILA! This one's 4 cm across.
