Can you post a photo so that we can see where you are in the process? There are a couple of ways to finish your quilt. You could do the pillowcase method, where you lay your backing and your front right sides together, place the batting on top, baste, sew around the perimeter for all but about 12 inches and then turn everything inside out. The other way is to lay your backing face down, batting on top of it, then top right-side up on top of that, baste, quilt, cut off the excess and bind.
