I have not done a 10 minute blk quilt but there are several on QB. Have you seen the Youtube tutorial on the 5 minute blocks? Basically it is half of the 10 minute block but it makes a really cute scalloped border design. If you look under tutorials on QB, you will find a 11 minute block that someone posted. It is very cute with an extra step to make a flower block with the 3 D center.
