I love it too! I also have a little trouble lining up the units to sew them together. I just figured out that a great way to do it is to use the glue pen!!! Yes...glue! I works much better than the pins for me. I'm doing the Jane quilt and those tiny blocks ..you have to be perfect on the triangles..I found the glue to be just the right thing. The one I use is a Sewline fabric glue pen.
