I am going to sandwich lap/nap size quilts. As I was laying top on batting I noticed that there is not much extra around the outside. I am using Hobb's twin size packaged batting that measures 72 x 90 for this nap quilt that measures 69X 85. I bought twin size batting thinking that it could be used to make twin size quilts or these nap quilts. But if the finished size of the twin quilt is ususal 72 x90 {with no drop) and the cut size of the twin batting measures 72 x 90 how can I use this twin size due to there is no extra to allow for quilting? Does this mean that you need to buy one size up to allow enough extra for quilting? Is this true fo all packiaged battings? I bought twin for these quilts so I would not have to cut too much off. I am going to email Hobbs and mention this to them. Perhaps they should make piece 3 inchs larger to allow for quilting.
