This version omits that fleece layer, giving you more of a blanket, less of a mat. The first version is great and extremely warm, but not very flexible which is necessary to snuggly tuck a munchkin in their car seat. So, if you love the Granny Quilt, but want a thinner option, try this!
My blanket after quilting and trimming.
The technique is simple. Layer your pieced granny afghan on top of a piece of flannel (or cotton, but flannel is so cozy). Be sure you have plenty of fabric so it hangs past the edge of the afghan. I left about two extra inches on each side. The last thing you want is the fabric to creep in while you sew leaving a gap.
Pin at the corner/intersection of EACH granny square. I know this sounds like overkill, but it serves two important functions.
First it keeps the layers from shifting and stretching. The afghan will have a lot of give and having it well pinned will keep you from ending up with a distorted blanket.
Second, it helps to know exactly where your pins are. They get lost in the afghan and if you know you have one at each intersection, you will not leave any behind to stab an unsuspecting person.
Now sew. I run along the edges of the squares, but you can do whatever you wish, it's your blanket. I do all the lines in one direction, then all the rows that run across, forming a checkerboard pattern. Go slowly! You have to do this with the crochet side up (so you can follow the lines) and it can easily get hooked on the presser foot. Finish by sewing around the edge of the blanket. This will make it easier to sew on the binding.
Trim any extra fabric from the edges.
Now bind and you are done! Don't know how to bind? See the simple technique I use here .
