The satin binding is pretty simple. It's 2" wide, so I lay the quilt flat & trim it with my rotary cutter to about 1 1/2" from the edge of the quilt. Then pin the binding down one side of the quilt about every 6" leaving about a 6" tail.
I use my walking foot to avoid the front & back slipping & attach it with a straight stitch, a wide zigzag, or any decorative stitch. Stitch all the way to the end, then miter the corner and pin the next side. When I get back to the beginning, leave another 6" tail, overlap the beginning by one inch, making sure both ends are cut straight. Then pin the ends, right sides together with lots of pins because they're slippery & bias cut so they'll shift if you let them. Then sew the ends with a 1/2" seam allowance. I don't think 1/4" is enough because the ends fray easily. Then press the seam open, pin the binding to the quilt & finish sewing.
The satin bindings come in 4 3/4 yard packages, just right for a 36" square quilt. Have fun!
