Timberlea ... I hear you on the Magic Sizing ... for some reason, they ship in their Spray Starch, but do not send the Sizing North of the 49.
I use it .... and whenever I hear of someone going cross-border shopping, I plead for them to bring some back with them.
My Sizing Stash is cherished almost as much or more than the fabric stash .... it can replaced, the sizing is a scarce commodity!
