I designed this very cute rose pattern in under 5 minutes, so I know you can make it up just as quickly. I like patterns without a lot of fuss and this one is certainly fuss-free. Grab a small bit of leftover Loops & Threads Charisma in your stash somewhere or for a smaller rose use Vanna's Choice.
Crochet 3 hdc in first chain, 2 hdc in next 19 chains, 3 hdc in last chain, slip stitch in chain on other side. Tie leftover yarn and fasten off.
Coil petals so that it resembles a rose, and sew in the center. Fasten off and weave in ends.
Sew the rose on a scarf, hat, or headband and voila! You have a gorgeous embellishment to decorate your accessories.
