Hi newnana - wow that was fast!
Now you need to make your sandwich!
Cut your backing fabric a couple of inches all round bigger than your top and put it right side down on to a flat surface - table or floor. I like to put a piece of masking tape across each corner to hold it in place. Then lay your batting the same size as your backing over the top and smooth out the wrinkles; then your lovely top, right side up. Then you have you bast it together. Some of the ladies on the board use spray or a gun but I do it the old fashioned way with needle and thread. You want ot make lines of stitches about 4" apart in both directions. Your stitches can be around an inch long. Then you take up the tape and it's ready for quilting! I don't know if you want to do this by hand or machine? If it's machine then I'm useless so hopefully someone else will jump in and help!
