Here's how I make fabric poinsettias. I make a lot of teeshirt craft things and as a result, I have an enormous pile of sleeves. This is how I'm putting them to use. (BY THE WAY, you can make these out of any fabric you like, felt is also fantastic!!)
Adding more... I scribble sew some circles in the middle to keep it supported. Here you go, pretty messy but it doesn't matter, we're going to cover it up!
Here's my two waiting for their bright yellow rose centers. For each center rosette, cut a strip of teeshirt 10 inches long and about an inch wide, they curl, that's fine. Make a knot in one end and start rolling and twisting the knot clockwise. Twist the strip as it goes around. *I am going to make a video of this but don't have enough hands at the moment* Glue the rose every couple of twists to be sure it stays together. Be FREE!!! :)
The rosette will look like this. I glue the end to the bottom of it to keep it out of the way. Trim the back flat(ish) and hot glue it to the center of your poinsettia. I press down hard with the heel of my hand to flatten it a bit and ensure a good seal. Voila!
Toss them on a table for decorations, use them individually on chargers for a little pop of color or sew them all together (which I'm going to do) to make a table runner/centerpiece. I'll post pics when it's done but I wanted to get the play by play up.
Please send me pictures of the ones you make!! I love to see the creativity!
