Cross-stitch prep for math nerds
5 hours ago
- The most challenging aspect of cross-stitch is determining the correct quantities of supplies, which can be solved using math and geometry.
- Always round up calculations to the nearest integer to avoid underestimating supplies that could force compromises or restarts.
- To frame a pattern, first pad it to a square with side length n (the longer side) and center it; then create a circle of diameter n inside the square, scaling the square by a factor between 1 and 1/√2 if needed.
- Stitch count c (stitches per inch) determines detail and size; halving the count quarters both the actual size and thread needed.
- The minimum hoop diameter is calculated as d_min = (n√2)/c, where n is the pattern's side length in stitches.
- The theoretical minimum thread length for n stitches of the same color is (1/c)(4n-1) inches, but always buy extra to account for tension and knots.
