US yarn in the UK
Patons Classic Wool Worsted in the UK: closest UK yarns
The maker’s online shop, Yarnspirations, sells it to the US and Canada, and LoveCrafts UK lists it but had none of its 57 shades in stock on 4 October 2026. The closest UK swap in the yarns we track is Paintbox Simply Aran: 100% acrylic, 184m per 100g against 177m, and 18 knitted stitches to 10cm on its ball band against 20 on the maker’s. It’s 100% acrylic rather than 100% wool, so it will feel and wash a little differently. If the pattern is felted, use a 100% wool (not superwash) aran instead: acrylic won’t felt.
Best UK swap: Paintbox Simply Aran · 56 shades in stock · from £2.60 a ball

How many balls to buy
Buy by length, not by ball: a ball of Patons Classic Wool Worsted in a solid shade holds 177m (print and multi shades often come in smaller balls; check the label) and a ball of Paintbox Simply Aran holds 184m.
- 1 ball of Patons Classic Wool Worsted (177m) → 1 of Paintbox Simply Aran
- 3 balls of Patons Classic Wool Worsted (531m) → 3 of Paintbox Simply Aran
- 5 balls of Patons Classic Wool Worsted (885m) → 5 of Paintbox Simply Aran
- 10 balls of Patons Classic Wool Worsted (1770m) → 10 of Paintbox Simply Aran

Before you swap
US “worsted” (weight 4) sits between UK DK and aran; most worsted patterns work in a UK aran, but a lighter worsted can be closer to a heavy DK. Make a 10cm swatch in your swap yarn with the pattern’s hook or needles and compare it with the tension above. If your square is bigger, go down a size; if it’s smaller, go up. Swapping fibre changes the feel and the wash: acrylic for acrylic, cotton for cotton keeps a pattern behaving as written.

How we rank swaps: one combined score for closeness in metres per 100g, knitted tension on the ball band and fibre, with a small penalty for yarns with fewer than 10 shades in stock and for a chunky standing in for a worsted.
