How it works
The workflow, examples and limits behind every tool.
Cross-wrap ribbon ↗
Length = 2L + 2W + 4H + bow allowance.
Example: 20 × 15 × 8 cm box and 60 cm bow allowance require 162 cm.
A rectangular cross-wrap only. Allow for knot bulk, stretch and a test cut.
Bow length ↗
Length = loop count × ribbon length per loop + 2 × tail + knot allowance.
Example: 4 loops at 20 cm, two 15 cm tails and 10 cm knot allowance use 120 cm.
Loop length means ribbon consumed by one loop, not the visible loop width.
Spool cuts ↗
Pieces = floor(spool metres × 100 ÷ (piece cm + waste cm)).
Example: 10 m spool, 120 cm pieces and 5 cm waste per piece give 8 pieces with no remainder.
Identical cuts; leftover is not a usable extra piece unless it meets the full cut requirement.
Batch cost ↗
Cost = quantity × (ribbon cm/100 × price per metre + extras per gift).
Example: 10 gifts, 162 cm each, price 0.5 per metre and extras 1 each total 18.1.
User-entered prices, one currency, excluding labour and taxes.
Local work, explicit limits
Each workspace reports its input and file limits. Imports validate the supported format before asking to replace saved work. Plain text is displayed as text, never executed as markup. Both languages use the same tools; the root address always opens in English, with Chinese under /zh/.
