This is a "pooling" project. There is a lot of free information in the pooling forum and many free patterns in Ravelry.

The e-book Just Pooling Around contains all the information as to how-to create your own patterns with this technique and "pithy" patterns for the samples.

How to analyze your yarn - will it pool?
How to cast on.
Several lace charts and how to use them within your stitch count.

Lots of pictures and ideas!
