I just finished making the top of a quilt to fit a double/full size bed. It covers only the top of the bed. When should I add the borders? Should I put together and quilt the top and then add more batting around it when I add the borders? Or should I sew the entire quilt including the top and borders before adding the batting and backing? Thanks. Even though I have been sewing over 50 years, I never had lessons or learned the proper way to do it. I just muddle through and usually get lucky with the finished product.
