Choosing knitting & crochet yarn comes down to matching fiber, weight, and format to the project-not simply choosing the lower price. A 100% cotton #4 worsted yarn and a lace/super fine Suri alpaca yarn are aimed at noticeably different kinds of work. Here's the clearest way to choose between them.
Quick verdict
Choose Pure 100% Cotton Crochet Yarn for cotton projects such as washcloths, dishcloths, facial rounds, afghans, and blankets. Choose Peru Suri Alpaca Wool Yarn when you specifically want a lace/super fine yarn in a large cone format. The listed prices are $9.49 and $29.00, a $19.51 gap, so the project's required weight and fiber should lead the decision.

Where each yarn wins
Pure 100% Cotton Crochet Yarn

This yarn has the clearer fit for everyday cotton crochet and knitting projects. Its worsted medium #4 weight is positioned for projects that should work up without becoming overly bulky, while the cotton fiber is described as breathable, absorbent, and suited to washable household makes. The matte finish also fits projects where a non-shiny surface is desirable.
Peru Suri Alpaca Wool Yarn

The Suri alpaca option stands out for its specific lace/super fine weight and cone presentation. It gives fine-gauge project planners a large 970g amount in one format, with a cream color and Peruvian Suri alpaca merino fiber content. That makes it the more direct choice when the pattern or design calls for fine yarn rather than worsted medium.
Product notes
Pure 100% Cotton Crochet Yarn
Pure 100% Cotton Crochet Yarn is the practical pick for projects that call for 100% cotton and a worsted medium #4 weight. The description specifically names washcloths, facial rounds, soft dishcloths, throws, and blankets, so it has a broad household-project role. Its matte, absorbent cotton character is another concrete reason to choose it for those uses. The limitation is the 85-yard amount in each 50g skein: a project with substantial yardage will require planning around multiple skeins. It is also firmly a #4 yarn, so shoppers seeking a lace/super fine weight are looking at a different yarn category rather than a like-for-like substitute.
Peru Suri Alpaca Wool Yarn
Peru Suri Alpaca Wool Yarn is the better match for a project that calls for lace/super fine yarn and a cone format. Its fiber description identifies Peruvian soft Suri alpaca merino yarn, and the cream color offers a neutral starting point for a fine-gauge design. The 970g cone is a concrete reason to choose it when you want a substantial amount in a single spool-style format. Its limitation is the fine weight: anyone planning around a #4 worsted medium pattern would need a different weight choice. The cone presentation also differs from the cotton yarn's 50g skein format, which matters if small, separate skeins are central to your project setup.
Final choice by use case
- For washcloths, dishcloths, facial rounds, afghans, or blankets: Choose Pure 100% Cotton Crochet Yarn for its 100% cotton fiber and worsted medium #4 weight.
- For lace or super fine projects: Choose Peru Suri Alpaca Wool Yarn, whose stated weight and Suri alpaca merino fiber directly fit that brief.
- For a large cone format: Choose Peru Suri Alpaca Wool Yarn with its 970g spool cone.
- For a smaller skein format: Choose Pure 100% Cotton Crochet Yarn, presented in 50g skeins with 85 yards each.
The deciding question is simple: do you need a cotton worsted yarn for substantial everyday projects, or a fine Suri alpaca cone for delicate gauge work?
