Harder than it looks
It looked really cool and I watched the video but when it came to cutting the large pinwheel I ended up messing up and lost four of the pinwheels. So my quilt came out smaller..my pinwheels we're not the same size as theirs so my cuts were a different size and trying to figure out the cuts into threes was not that easy. Also make sure you have one of those spinning cutting boards as I am sure it will help alot.
