I've made this type of ribbon wreath! They are fun. I did all pink and girly pink patterns for my daughters' pink birthday party and now it hangs on her closet door.
I've also done one for my grandma.
I search for wreaths in the thrift stores.
I've used the straw wreaths (left in the plastic), foam, AND the triple wire wreath form sold at HL.
You can also use a wire hanger bent into a wreath form. You can also head over to home depot and get some pipe insulation and turn that into a wreath form with a piece of duct tape! ( http://pinterest.com/pin/48476675/
