Making product information easier to use: which tool does what, which specifications matter, and where a claim still needs checking.
Research you can follow
John organizes manufacturer documentation, product-listing details and practical decision criteria into the guides on this site. The goal is to help readers choose and use yarn-preparation equipment without confusing a swift with a winder or transferring specifications between similarly named models.
The site does not claim professional craft qualifications, personal testing or laboratory findings. Read our methodology for how products and sources are handled.
