The expression goes that you get what you pay for, but I've found that there are LOTS and LOTS of high quality free patterns to be found online if you just take the time to look for them. I will try to share links on my blog to some of the patterns I've found and have particularly enjoyed making because I think you will enjoy making them, too. Be sure to give your love to the original designers who have so generously shared their work!
I found this Shells and Trellis Hat pattern at the Halos of Hope website. Their very worthwhile mission is to provide handmade hats to cancer patients in need. Go support them or donate a handmade hat to your local cancer center today because it's a great thing to do.
Update: Halos of Hope has had to suspend its operations, although its website is still online. So anywhere I've suggested that you, my fellow yarncrafters, should donate your wares to Halos of Hope, please amend that to say "your local cancer center" or any other suitable charity program in your area. The pattern for the Shells and Trellis Hat is also available on Ravelry here.
