Círculo Anne 500 vs EuroRoma Fiore

Technical verdict: Círculo Anne 500 vs EuroRoma Fiore

Weight category, yardage and value per ball

Círculo Anne 500 is a Super Fine (CYC 1) yarn while EuroRoma Fiore is a Lace (CYC 0) yarn. Because they sit in different weight categories, a pattern written for one will not give the same size, gauge or drape with the other unless you change the hook and rework the stitch counts after a swatch.

Círculo Anne 500 is the longer yarn per gram, with 340 m per 100 g against 322 m per 100 g for EuroRoma Fiore, a difference of 6 %. For the same 1,000 m of yarn, the project weighs about 294 g in Círculo Anne 500 and 311 g in EuroRoma Fiore. A lower m/100 g figure means a thicker or denser strand, so the heavier yarn will also make a slightly thicker, warmer fabric.

Per ball, Círculo Anne 500 holds 500 m in 147 g and EuroRoma Fiore holds 322 m in 100 g. Five balls of Círculo Anne 500 (2,500 m) are replaced by 8 balls of EuroRoma Fiore, and five balls of EuroRoma Fiore (1,610 m) by 4 balls of Círculo Anne 500. Always convert by length, never by weight or by number of balls.

Drape, fibre and texture

Both yarns share the same fibre family: Círculo Anne 500 is 100 % cotton (mercerized) and EuroRoma Fiore is 85 % cotton, 15 % other fibres, so they wash, block and wear in a similar way. Cotton is inelastic and absorbent: stitches look crisp and defined, the fabric holds its shape in amigurumi, bags and dishcloths, but garments can feel heavy and stretch downwards when wet.

Their construction differs: Círculo Anne 500 (Mercerized) versus EuroRoma Fiore (Plied). This changes stitch definition and how easy it is to see your stitches, so expect a different look even at the same gauge.

Hook size and gauge

The ball bands recommend 1.8–2.5 mm for Círculo Anne 500 and 2 mm for EuroRoma Fiore. The ranges overlap at 2 mm, which is the safest hook to start a test swatch for either yarn.

At least one manufacturer does not publish a reference gauge, so work a 12 × 12 cm swatch with your usual hook before comparing sizes.

Verdict: can you swap them?

EuroRoma Fiore can replace Círculo Anne 500 with some adjustments (Match Score 67 %). Expect small differences in gauge or drape: swatch first and be ready to change the hook by half a size.

Círculo Anne 500 gives more meters per ball, so you will usually buy fewer balls.

Whichever you choose, buy all the balls for a project from the same dye lot and keep the ball band for its care instructions.
