I can't measure how much time and money these tape measures have saved me! I always keep two on hand--one in the car, one in my purse. They're especially important if you buy secondhand. No more guessing about the length of those thrift store draperies or if that salvaged French door will fit in my kitchen. Mini tape measures are also great for distracting a fussy kid in a doctor's waiting room!
