The "All-in-One Quilter's Reference Tool" is excellent.
For those who have trouble doing the math for yardage or
to calculate the size of a quilt with sashing or on point, etc.
There is so much in that little book. Lot of charts for cutting
different shapes, etc. Worth every penny.
No affiliation whatsoever.
My only complaint is that the print is very small.
Get your magnifying glass ready.
