the software has a statement from brenda this is it.
Amount
In my Dear Jane book, I recommend five yards of background fabric. I wish I could tell you that was a typing mistake. The truth is that I couldn’t image anyone making this entire quilt – I have learned a great deal since 1991 – and I thought 5 yards should make anything! (A special thank you to all of you Dear Janes.) We now have a rule of thumb for buying fabric for a Dear Jane:
A. Hand pieced –- you will need about 8 yards of background.
B. Variety of techniques – hand piecing, machine piecing, some foundation piecing – you will need about 15 yards for your background.
C. Foundation piecing – when you plan to use this technique for most of your blocks, you will need about 20 yards of background fabric
