That’s a tough one! The only thing I can think of (not knowing what your flowers look like and how many you actually have) would be to do scarves first and then join those scarves to have a small blanket. Does that make sense? Here is a tutorial that explains it pretty good: http://bit.ly/WlNOZj – at least how to make flower scarves.
Other than that – I don’t know. To join 5 petal flowers is harder than 6 or 8. Good luck!
