These are the calculators on the studio list. Each page below opens that calculator and explains the math.

BindingStrips and yardage for a double-fold edge.
Bias bindingThe square you cut for a continuous bias strip.
BackingPanels, seams, and yardage for the back.
Diagonal backingJohn Flynn's seam, when it actually saves fabric.
BattingThe package that actually fits the quilt.
