There a 2 ways you can do binding. If you want your binding to be the same as your backing then you can cut this extra fabric to 2", press fabric in half, fold it over sandwich and then stitch to the front. If you do not want the binding the same then you need to trim the all layers including backing even. Then cut 2 1/2" strips fold in half and attach to the sandwich. It can be attached to front if you want to hand stitch binding down or to back if you wan to machine stitch binding down. There are many good tuts on attaching binding. do a search on thise board oro the internet and you will find many. Good luck!!!!
