Measure length and width. Multiply by two to get the length needed for binding.
Make sure the binding has two sides, or fold it in half lengthwise to create a two sided length.
Pin the binding down one length of the blanket making sure to catch both sides of the satin binding.
When you reach the end of the first length, pin the binding to the edge. Using a 90 degree flat-fold, turn the corner. Remove the initial corner pin and use it to pin down the flat folded corner so there are no pins hidden in the folds.
Repeat the process along the edge, turning all corners
Press down all corners. Make sure pins are in place and none are hidden in corner folds.
Stitch around all edges so as to catch the blanket and two layers of the satin binding. Use decorative stitching or a zigzag stitch to enhance the edges.
