pbadder....I live in So. Cal... I would suggest to go to another PO. The reason being is that The different Post Office around me give me different prices......not only that the clerks in the post office will quote different prices. My closest P.O. gives me the fairest price.....65Cents. As long as it fits in that little slot thing they have it is a go. Doesn't matter if it is material or a letter. But even in my closest P.O., one of the clerks wants to charge me parcel price and she is not a pleasant person. I thought it was me that thought that but happily I heard others complain about her. Anyways....try a different branch and see what they say.
I too am excited about playing with all the fabric that has been shown so far. I am getting excited.
