I've ordered *several* of these kanzashi flower makers, so I'll be basically copy/pasting my reviews on them since I feel the same about all of theme.I got these to use with fabric ordered from spoonflower.com - and one thing to note is that all of these are VERY small, I'd say that your design needs to be micro levels of tiny in order to be noticeable on the petals. The large, however, is much larger than the small, and looks pretty nice with a small (not too busy) pattern on it.The patterns are all very straightforward to use, the holes are numbered, and if you take your time to gather the fabric nicely when you're pulling the thread, they're lovely!I made mine using cotton poplin fabric, but I also attempted some using a cotton with some stretch and a brocade fabric that also had some stretch. They come out best with the basic cotton poplin - very little fraying and the fabric folds very well. The fabrics with stretch, though, were much less cooperative, and want to fray WAY more while being worked with.I've also tried just hand-folding these, and it takes me significantly longer to do. Not to mention the results aren't nearly as uniform.But, I make flowers using these templates, glue them with E6000 to a small (about 1" diameter) circle of felt, cover a button in the same or a coordinating fabric (3/4" buttons work nicely with the small, 5/8" for x-small, and 1" for large), sew that in the middle after the glue is dried, and then attach the finished flower to a brooch, headband, or necklace. Using strong adhesives and a high-strength hand quilting thread, I've yet to have any of my crafts come apart!If you're thinking of picking these up, they're fairly cheap and fun to use. Generally, I prefer the 5 petal flowers to the 10, but you can mix petals for different looks as well.
