I've only made one so far:
I plan to make more of these, and have already prepared fabric strips to make them. The width of your fabric dictates the finished size. This star began with fabric strips 4 x 16".
The tutorial that I used was from Mr. Domestic. He is so much fun to watch.
Another wonderfully written, step-by-step tutorial with photos is from Crafting Rainbow.
These are so much fun to make, and would make a cute present topper.
Happy crafting,
Val :)
