the amount of quilting necessary on any quilt is dependant on the chosen batting- some batts need to be quilted every 2"- others allow up to 10" between quilting lines= you need to check the batting you are using and see what it says in necessary. if using a batt with scrim (like warm & natural) you have plenty of quilting covered- if using hobbs heirloom you would need to add more (it requires quilting every 2") there are many different recommendations....check your packaging
