Find the seam-line radius and the inner and outer cut radii for a quarter, half, full, or double circle skirt.

Lay out rectangular pieces on a usable fabric width, with an optional vertical repeat and an explicit rotation choice.

Scale a pattern measurement from an original and a target, or from a print percentage.

Add a separate allowance to each edge of a finished rectangle to get the cut size.

Add waste, round the quantity up to a purchase increment, then apply your price and tax.

Compare vertical and horizontal backing panels, then round the purchase length up to the increment you set.

Estimate straight-grain binding strips, including the length lost at each diagonal join.

Cut straight, butt-joined borders one layer at a time and estimate the strip length to buy.

Count blocks across and down for a target size, with between-block sashing and outer sashing kept separate.

See the area-based square that contains the binding length you need. It is not a guaranteed cut yield.

Turn a stitch count and fabric count into finished size and a cut size with the margin you choose.

Estimate fabric for a simple two-face cushion or a simple box cushion with one boxing strip.

Count equal curtain widths, add drop allowances and a vertical repeat, then round the purchase length up.

Find the flat width and the number of equal panels or fabric widths, without calculating drop or yardage.

Convert a finished coverage width into flat fabric with either a fullness ratio or an explicit pleat take-up.
