I really thiink you also need to know where to go in New York to do this. This weekend New York is closed down because of a blizzard. Tell us where you will be so we can find shops for your daughter and husband that will not be that out of the way. Most American fabric and quilt shops have the rulers you will want. Also the Needle threader is must when you are binding your quilts. Below are some links to help you decide what you may want.

Joanns and Hancocks are usually in every major city. One or the other. I hope this helps.
