Craft Tools

Work out how many beads a necklace, bracelet or anklet needs from your pattern and finished length. Define a repeat of up to four bead types with sizes and colours, subtract the clasp, and get per-colour counts and a strand preview.

Convert crochet hook sizes between US letters and numbers, UK/Canada numbering and the metric mm scale. Pick a size in any system to see every equivalent, the recommended yarn weight and a steel thread-hook table.

Estimate how many skeins of embroidery floss a cross-stitch project needs from the stitch count, Aida count, strands used and stitch density. Gives thread length per stitch, total length and skeins to buy, with a waste buffer.

Work out the finished size of a cross-stitch project from your pattern stitch count and fabric count for Aida, evenweave or linen. Supports several fabric types, adds framing margins, and gives inches, centimetres and millimetres.

Estimate how much embroidery floss you need by stitch type: satin fill, backstitch, stem, chain outlines and French knots. Get total length in metres and yards, the skeins to buy and how many working cuts to prepare.

Calculate the exact amount of fabric needed for sewing projects, quilting blocks, garments, and home decor. Features pattern layout visualization, waste minimization, directional print support, and detailed cutting diagrams.

Convert knitting needle sizes across US, UK/Canada, Japanese and metric systems. Enter a size in any system to see every equivalent, a to-scale thickness diagram, the closest match where none is exact and a recommended yarn weight.

Work out how many stitches to cast on and rows to knit for a sweater, scarf, blanket or any rectangular piece. Enter your gauge and finished width and length to get the cast-on count, total rows, a scaled diagram and a yarn estimate.

Work out the origami paper size you need for a finished model size. Pick a classic model - crane, masu box, lily, frog and more - or calibrate from your own test fold, then get the exact square to cut and the closest standard sizes.

Account for clay shrinkage when sizing pottery. Calculate the fired size of a wet piece, work back from a target fired size, or measure your clay body's real shrinkage from a test tile, with earthenware, stoneware and porcelain presets.

Work out how much binding and fabric a quilt needs. Enter the quilt size, strip width and fabric width to get total binding length with corner allowance, strips to cut and yardage to buy, for straight-grain or bias, single or double fold.

Calculate how much yarn (yards/meters) you need for sweaters, blankets, scarves, and other knitting or crochet projects. Estimates based on yarn weight, gauge, project size, and stitch pattern.
