I have a great book, 100 Flowers to Knit and Crochet, by Lesley Stanfield. The patterns are divided roughly in half between knitted and crocheted flowers. There are also patterns for leaves and butterflies. Unfortunately, I can't remember if there is a pattern for forget-me-nots. I am at my Mom's house right now, so I can't check!
I looked up Forget Me Nots and this pattern looks a lot like them! If you did them in purple they're be perfect! It's unclear if they are free or not so you'll have to check. http://nonipatterns.com/collections.php
When asking questions ALWAYS post the name and a link for the pattern if you have it.
