You have permission to print all free crochet patterns and other craft and projects for personal use, but not for redistribution anywhere, either online or offline. You may not sell the patterns, nor give them away to anyone. You may link to all patterns (links are very much appreciated), but do not copy whole patterns unto your website or blog.
You do have permission to sell or donate to charity anything that you make from the patterns,provided that you do not go into mass production. You may sell your items offline in shops, craft shows and carnivals, as well as online on websites like Ebay, Etsy, E-Crater and others, as well as on your own website or blog if you have one.
Starting a crochet or craft business can be very rewarding and financially satisfying once you succeed. Getting started can be tough, but once you get going all the hard work will be worth it.
The internet has made it very easy for anyone to start a craft business, as you do not need any start-up fees, nor do you need a lot of products to sell. Therefore anyone who can crochet or craft can start an online business.
