Why can two wool sweaters have different ironing labels?
Two labels can both say merino and still differ because the knit, the finish, and any undeclared blend percentage change heat and wash. The fiber name is not the care instruction. Use the label sewn into that garment. A fabric page that does not state care cannot fill the gap.

- Fiber is not a wash cycle.
- Finish is often the hidden variable.
- Do not copy one sweater's iron onto another.
What to check
Look for blend lines and the iron symbol, not only the word wool.
If you are sourcing the cloth, ask for care before you print a label.
