it depends on where the kit is coming from- some shops just barely give you enough---you had better be accurate--others are very generous -
Jinny Beyer patterns are all advanced and for some reason some shops feel that means you will not make mistakes- and they are very stingy with the fabric cuts-
some how ever take into account that happy customers come back- and are more generous-
i would try to read some comments from customers who have purchased kits from the source- to see what they are saying about the kits they have purchased.
