Using the resolution of 72 or 75 will make your pictures small. If you are using, EQ5, I don't believe that the program will enlarge the fabrics.
EQ 6 & 7 will do that for you.
Some scanners will allow you to choose your resolution. Or, you may have to crop.
(I talked to my sister about getting the smaller resolution, and she said to ask our children! They can do anything!)
