Advertising and affiliate disclosure

The Craft Mat is free to use. We cover our costs in three ways:

• Display ads, labeled as advertisements and kept away from calculator buttons and results.
• Affiliate links to yarn and fabric shops. If you buy through one, we may earn a small commission at no extra cost to you. Affiliate links are marked where they appear.
• Our own printables, such as planners and trackers, sold on our site, Etsy or Gumroad.

Ads and affiliate links never change how a calculator works or what it tells you to buy.
