I found this flannel material at Jo-Anns and instantly knew I wanted to make it into a blanket for my baby girl.
First, make it square - I think the fabric was 44", so I just had them cut that same length. But you could fold it diagonally in half and cut the edge so that it's a square. Then I traced a salad plate around the corners to get the nice rounded corners.
I scanned the giraffe on the fabric and enlarged it to the size I wanted for an applique. So I used wonder under and fused it to the bottom corner and then hand stitched it with a dark thread so that showed up.
