Advice needed - Treadle Yard Goods

[ladymurmur]

My sister won a $20 gift certificate to Treadle Yard Goods in a silent auction, and gave it to me. She actually thought it said 'Yarn' instead of 'Yard', but either way, I appreciate the thought! I've only been there once, ages ago, and what I remember is that everything was rather pricey. So...

Any suggestions on how to spend $20 at Treadle Yard Goods? Will $20 go very far?

Thanks!

EDIT: The gift certificate expires on 6/15, so I can't save it for my next big project. Also, is it possible that the store does not have a website? I've found review after review, but no website.
