Is This Enough

Is a total of 1250 yarns (10- 50 gram balls of worsted weight) enough tomake a womans sweater? I don’t have a pattern yet. Thanks

Depends on the size, but unless it’s a very large size, yes, that whould be plenty.

A simple basic sweater in an small size should be fine, but if you have a longer one or a larger size you might need more.

Most patterns you have to figure out yourself based on the yardage in the yarn you have vs size. Here’s one I had bookmarked that I plan on making and it gives yardage.

Here’s a site that lists estimates.
