@RedOak Actually as long as you have a few stitches here and there to keep the middle from ballooning out it can make a nice thicker blanket (especially since fleece has gotten thinner these days).
When my daughter was younger I bought one piece that had flower patches sewn on it and another plain colored one that matched. 2.5 yards of 60" fleece makes a nice twin blanket.
I rolled the edge plain colored one on to the “front” to frame the flower side with about a 1.5" strip of that color (didn’t cut it, just made the flowered on a tiny bit smaller than the plain colored one). Then in the middle of each flower put a stitch through to the other side. She loved that thing. It was warm and pretty. Only took me about 3 hours. I had been madly sewing it christmas eve after she (finally) went to bed.
