Bernat Blanket vs Premier Parfait Chunky: Check Gauge Before You Swap
Bernat Blanket and Premier Parfait Chunky are candidates for a substitution trial, not a confirmed one-for-one replacement. Both product pages list polyester, super-bulky weight and an 8 mm crochet hook, but their published crochet gauges differ. Start with the pattern's target gauge rather than assuming that the matching hook size settles the question.
The specifications that affect the decision
| Specification | Bernat Blanket | Premier Parfait Chunky |
|---|---|---|
| Fibre | 100% polyester | 100% polyester |
| Ball weight | 300 g | 100 g |
| Length per ball | 201 m | 120 m |
| Listed crochet hook | 8 mm | 8 mm |
| Crochet gauge per 10 × 10 cm | 7 sc × 8 rows | 8.86 sc × 8.86 rows, converted from 4 in |
Sources: Bernat Blanket, 300 g and Premier Parfait Chunky, checked 25 October 2026. Bernat supplies the metric gauge directly. Premier lists 9 sc × 9 rows per 4 inches; conversion uses 4 in = 10.16 cm, so 9 × 10 ÷ 10.16 = 8.86. The converted figure is arithmetic, not a new measurement.
A matching hook is not a matching fabric
The published gauges are different even though the listed hooks match. That is enough to reject an automatic equivalence claim. It does not predict the dimensions of your own crochet: the samples were not worked by you in your pattern stitch.
Work a sample with the replacement, using the construction your pattern requires. Record stitch and row counts separately. If width agrees but height does not, a correct stitch count alone has not resolved the swap. For a shaped project, check the shape as well as the measured square.
The practical question is whether your replacement sample meets the pattern's needs. Neither manufacturer's label answers that on its own.
Replace metres, not ball counts
One ball of each is not the same amount of yarn. As a hypothetical length-only example, replacing 201 m with balls containing 120 m gives 201 ÷ 120 = 1.675, rounded up to 2 whole balls. The inputs come from the product pages; the calculation assumes the project still needs 201 m.
That assumption is the limit. A change in fabric or construction can change consumption. The calculation does not establish that two balls will finish an untested adaptation.
Before committing to a full project, record the sample's dimensions, tool, stitch pattern and yarn use. If the fabric fails the relevant test, revising the shopping quantity will not fix it.
Use the full yarn comparison chart to keep the specifications beside your sample notes, and the substitution guide to distinguish a size problem from a firmness or stitch-visibility problem.
