How DolyaCut calculates quilt yardage
Every length is in whole eighths of an inch, so there are no rounding surprises. Worked example: Lantern Path, Baby. It has 4 × 5 Lantern blocks (8" finished), 2" sashing between and around the blocks, a 4" border, 2½" binding and a usable width (WOF) of 40".
- Quilt size.
- Centre: 4 × 8 + 5 × 2 = 42" wide and 5 × 8 + 6 × 2 = 52" high.
- The border adds 2 × 4" each way, so the quilt finishes at 50" × 60".
- Strips for each cut. Strips = ⌈pieces ÷ ⌊WOF ÷ subcut⌋⌉.
- A: 20 squares at 4⅞" fit 8 per strip, so 3 strips.
- A: 49 sashes at 2½" × 8½" fit 4 per strip, so 13 strips.
- Border chain, sides first.
- Sides are 52½" each. Top and bottom are 42 + 8 + ½ = 50½" each. The total need is 206".
- Each straight join loses ½": ⌈(206 − ½) ÷ (40 − ½)⌉ = 6 strips.
- Binding.
- Perimeter 220" + 12" extra = 232".
- Each diagonal join loses one strip width: ⌈(232 − 2½) ÷ (40 − 2½)⌉ = 7 strips.
- Yardage. Add the raw strip inches, add the extra once, then round up to ⅛ yd (4½").
- A: 3 × 4⅞ + 13 × 2½ = 47⅛".
- Add one widest strip (4⅞") for 52", which rounds up to 1½ yd.
- Backing, with a 4" overhang: 58" × 68".
- Each seam loses 1".
- Horizontal seam: 2 panels × 58" = 116". Vertical seam: 2 × 68" = 136".
- The shorter is 116", which rounds up to 3¼ yd.
| Baby (50" × 60") | Raw + extra | Buy |
|---|
| A Background | 47⅛" + 4⅞" = 52" | 1½ yd |
| B Print | 52" + 4½" = 56½" | 1⅝ yd |
| C Accent | 37⅛" + 4⅞" = 42" | 1¼ yd |
| D Backing | 116" | 3¼ yd |
| Batting | 58" × 68" |
There is no industry-standard allowance. DolyaCut prints whichever policy you choose under every table, so the people using your pattern know what is included. These figures come from the designer's own cut list. They do not certify that a block goes together. Always test-cut.
