Good for you on finishing your top. I made one for my daughter many years ago. If you are adding sashing strips around the top do that now. and then make a sandwich consisting of the top, the batting and the backing. It's best done on a big table or the floor. Then you either baste through all layers or you pin them together using many, many pins. Make sure you backing and batting are larger than your top, you can trim these after you have quilted. Start quilting from the middle out. I use a PVC pipe frame and hand quilt but you can quilt it on the machine in the same manner.Remove the pins as you go. When your don trim you back and batting a little larger (1/4inch) than the finished top.The binding is the last thing to go on. I use binding I've made from material . Usually mine is 2 and 1/2 wide material I've pressed in half and sewn to the top side of the quilt. I lay the folded strip with the fold towards the inside of the quilt top and sew 1/4 inch all around the quilt.putting the ends one in side the other at the start/end point and then I flip it over and do a tiny stitch on the back side. If you have any questions there are many people on this site to help you when you get stuck.Watch some of the tutorials, they are really helpful Good luck, show us when you're done.
