I made just a plain white pillow and used fabric glue to attach the yo-yo flowers. I found this tutorial for the flowers here.
I also think I will have to check myself in to the yo-yo anonymous due to the slight obsession with the yo-yo flowers.
I found a cute mini-tutorial for these pillows here. Notice, the yo-yos again. These really were easy to make. Cut fabric and thread a needle.
I plan on making some more pillows, of course, when I can psych myself up enough to get out the sewing machine.
