As promised, I said I would try to find out where I got the patterns for my previous post
This website, called mypicot.com has a ton of beautiful pattern links. Knit as well as crochet. There are also tutorials and e-books available, which I have not explored yet. Almost all crochet patterns of MyPicot are presented as diagrams and have no written instructions.
Just click the photo to go to MyPicot. Then, forward to page 9 to find this beautiful Shamrock Edging. But, really, stroll through the website. I promise you will find many, many treasures.
Must have Adobe Acrobat Reader to download. Opens to a photo and diagram.
