Your blocks are beautiful! Back about 15 years ago, the 10 minute block was known as the '3-D Bow Tie'.Five blocks all cut the same size. Three of the blocks using the same fabric; one of them being the center; or knot.The other two fabrics being contrasting. It makes a very pretty quilt if you would arrange the completed four bow tie blocks; [or 10 minute blocks] in a circle. And then place four more blocks in another circle, without sashing, right next to them.Four of these now put together , [in a circle], leave a beautiful wide open space in the middle to showcase some lovely quilting. I hope this is plain as day, 'cause I'm not any good at sending pictures or drawings. This block is easier to sew than to explain.
