You want to use a little solvent as possible during a recrystallization.
Why? Because if you use too much your desired product will stay dissolved in solution!
This means that your percent recovery will be lower than it should be.

Example: if your recrystallization of 10g impure material worked fine using ~100 mL of solvent, then repeating the procedure with ~200 mL of solvent would definitely lower your percent recovery. Because the material is soluble in the solvent, using too much solvent means that more of the material stays dissolved.

When doing recrystallizations in an undergraduate orgo lab, be patient! Don't use too much solvent or you'll get a lower yield.
