I used one yard each of the printed fleece and the contrasting solid fleece. This made a blanket that's a nice size for a stroller or crib. Lay the printed fleece right side up on the solid fleece and trim all the edges so they are straight and even. Cut a square through both fabrics from each corner the same size as you would like the trim. I made a 6" square from cardstock and used that as a guide for each corner. Once you have the corners cut out, cut the edges into even strips (I did mine 1.5" wide). Now your blanket should look like the diagram below.
To "tie" the strips, make a small slit (about 1/4") with a seam ripper through both fabric layers ending slightly above end of strip cut.
Lift the top layer up...
and feed it through the bottom layer through the slit you just cut.
Once you feed the top layer all the way through, pull the bottom layer up so you can find the slit... and then feed the bottom layer through the slit...
pulling it tight to make the edge border.That's all there is to it. Although it's a lot of steps to show with photos, it's actually super easy to do. If you try it and get stuck or if you have any question, just e-mail me.
