Sometimes we just have to have a collection or particular print when we see it.
I am certainty guilty of this. And my hubby... Oh my! Went into a quilt shop one time with him for a cone of thread - he saw the newly released wizard of oz fabric collection - while I'm choosing my thread he was stacking bolts on the cutting table! That little $15 stop wound up costing over $200!!! And, its been 4-5 years, the fabrics are still in the bag, on the shelves- I've never figured out/found time to do anything with them.
Sometimes he is much worse than I am at self control.
