Dee Dee,
try www.villagequiltshoppe.com
they have lots of free patterns, and bunches of really inexpensive patterns.
I know they have several snowflake patterns. just do a search for them.
They also have a quilt pattern that has different snowflakes in each block.
I've used their patterns before, and they are accurate and well written.
If you don't want to pay for snowflake patterns, go to www.about.com/quilt. Thousands of free block and quilt patterns - and do a search on snowflake
