I've bought several. Somehow, they seem to work their way off my coat and get lost. I also decided to knit a poppy. I used the pattern by Laura Chau, which can be found by clicking here. It's a free pattern but she is asking for donations what she will give to the Canadian Legion. I made my donation.
Pattern: A Poppy For Remembrance by Laura Chau.
Yarn: Mary Maxim Starlette from my stash - worsted weight
Small amounts of #033 Dark Willow and $105 Berry Red.
The center of the poppy should be black but since the dark green was at hand I used it instead.
Needles: US #2 / 2.75 mm
Note: I made a small change to the pattern, making the red section a bit wider by adding one more round. Round 10: *(Kfb, k2) 3 times, Kfb. Repeat from * to the end of the round. 56 sts.Then, I went back to following the pattern as written.
