Recent find, is it a good one?

I recently purchased these fun looking yarns at the newly open Christmas Tree Shop in Fayetteville. I think they would be great for couching on under the sea blocks. When I read the label it states 'Do not iron'. Is this common with these types of yarn? They are 100% polyester. Should I strike them from my list of sea weed possibilities? I'd appreciate any input!

Pincushion Swap Part 2

So I recently received my pincushion from Wendy herself. Wendy made sure I received a treasure of a pincushion. And what a cute pincushion it is!! I love it. This pincushion held extra surprises because inside were some crazy quilting goodies. AND because she is such a very sweet lady Wendy included more crazy quilting goodies in the package. I am over whelmed!! Thank you Wendy!!
