The Windmill Swap quilt blocks are sewn together. Still deciding about the border. If I do a border, it will probably be smallish. A pinwheel is supposed to show up where the blocks intersect (white parts on mine) but you lose that with the tilt. There isn't that much tilt to the blocks, but it still breaks it up.
One of the reasons I tilted them is because when you do a swap, there is a good chance that the blocks won't all be the same size, so putting some type of border around them and resquaring the blocks helps even them out. Plus it adds a little more pizzazz!
Going to a quilt bed turning today at the Harrison County Fair today...should be fun.
