| Know before using | A measurement-generated draft is a starting block, not independent evidence of body capture, comfort, mobility, balance, garment ease, or production fit. The result depends on measurement accuracy, supported ranges, formula assumptions, selected options, and output handling. Review the service's privacy terms before storing body data and sew a representative toile before design, grading, or production use. | This is a unit-translation reference. It does not select, approve, or change a seam allowance; establish a universal fraction; interpret an unstated cutting or stitching line; or replace the exact pattern version, controlled specification, material and seam evidence, sample, production method, equipment, tolerance, or release authority. | PatternReview combines community reports, membership, education, advertising, and retail, so it is not a neutral or complete pattern index. Reviews are individual experiences rather than standardized fit tests. Confirm the exact pattern version, size range, measurements, fabric, format, errata, licence, seller terms, and current availability with the designer or publisher. Paid catalogue and search features do not establish an export route or continued access after membership ends. |

| Source and review | |||
| What the source establishes | PatternLab London's current drafting page says a user creates a measurement profile, selects a basic block or sloper, adjusts fit, dart placement, length, seam allowance, and sleeve options, then downloads the generated result as tiled PDF, AI, or SVG. The live catalogue names bodice, dress, trouser, and stretch blocks and displays a price before purchase. | NIST states that one inch is exactly 25.4 millimetres, and the SI decimal relationship makes one centimetre equal to 10 millimetres. The tool uses those factors, displays rounded equivalents, exposes the size difference to the nearest 1/16 inch when converting to inches, and preserves valid value, source-unit, and target-unit state in the URL. | PatternReview's current site exposes recent pattern, sewing-machine, and store reviews, forums, contests, classes, classifieds, a pattern shop, and a searchable review gallery. Its account FAQ says most participation requires a free activated account. Friends of PR adds advanced search, a personal pattern catalogue and wishlist, bookmarks, classifieds, a photo album, discounts, and other features through a recurring paid membership with a published email cancellation route. |
