Cut (42) 6.75" squares for each quilt. I used different shades of three different colors, but yours doesn't have to be rainbow-y. It could be scrappy or a single color or whatever you want.
Pair the squares together to make half square triangles. Trim the HSTs down to 6.25" and sew together the quilt top so that it is 6 blocks x 7 blocks.
When I was finished with the quilt tops I was a little stumped about what to use for backing. I wanted to use the same print in different color ways and I was convinced that I wouldn't find anything out there that matched both of my quilt tops. But I checked my stash and was delighted to find out that my fabric hoarding had paid off: I had enough of this Alison Glass print in orange and in blue to back the quilts. Yay for having too much fabric!
If you want a quick way to quilt a project, I highly recommend the "organic grid." It is one of my favorites. You don't have to mark any lines, just start sewing without making an effort to keep the lines perfectly straight. I have tried making my lines intentionally crooked, but it looks a little funny and I am pretty good at making my lines a little crooked without trying. This method gives the quilt a great feel and it is so fast.
My nieces are still in the hospital, but are just on oxygen while they get fattened up a little bit.
So I just need to get these in the mail so they are waiting for those sweet baby girls when they come home.
Finished size: 35" x 40"
