Check the footprint and cutting budget

70 × 24 − 35 × 12 = 1260 sq ft

The missing corner is split out of the footprint. Two rectangular panels meet with a six-inch overlap; the join has its own pin allowance. The finished perimeter is 188 feet. The cut budget reserves 1461 square feet, including 127 square feet in overlapping layers and 74 square feet trimmed from the footprint. The purchased 3 rolls provide 1800 square feet; 339 square feet remain as uncut stock.

Read each panel's cuts before buying

Panel 1 runs 12 feet along the strips and 70 feet across them, using the crosswise direction. The 13 strips cover 72 feet after side overlaps. Each strip uses 1 piece(s): 0 full-length pieces plus a 12-foot tail. One roll supplies 8 complete tails; the panel requires 0 full-piece rolls plus 2 tail-piece rolls. Total full-width cut length is 156 feet. Panels do not share remnants.

Panel 2 runs 12.50 feet along the strips and 35 feet across them, using the crosswise direction. The 7 strips cover 39 feet after side overlaps. Each strip uses 1 piece(s): 0 full-length pieces plus a 12.50-foot tail. One roll supplies 8 complete tails; the panel requires 0 full-piece rolls plus 1 tail-piece rolls. Total full-width cut length is 87.50 feet. Panels do not share remnants.

What changes with a wider overlap?

Changing this exact footprint to twelve-inch overlap produces 3 rolls and 1554 square feet of cut fabric, including 269 square feet in overlap. Its trimming allowance becomes 25 square feet. A changed overlap may alter the preferred direction; the program recomputes both rectangular choices.

What changes with closer pins or a fixed direction?

At twelve-inch spacing instead of twenty-four inches, this six-inch-overlap layout reserves 464 pins: 188 around the outside and 276 on seams. With the original spacing and overlap but a forced lengthwise direction, it requires 5 rolls, 1890 square feet of cut fabric, and 223 pins. These alternatives keep the same ground dimensions; they change the layout or fastening budget.

Before using this estimate on site

Confirm the actual package dimensions and include any border extensions. Pin counts treat each open seam's endpoints independently, and do not add anchors for plant holes or interior field positions. The roll-size table compares complete cutting plans rather than dividing ground area by package area. Automatic direction checks two directions per panel and does not search every possible patchwork arrangement. Any reduction through offcut reuse requires a separate drawn cut list.
