I bought a batik fat quarter mystery once, thinking that if there were browns/neutrals in there it would be OK as I don't buy those and it would be good to round out my stash.
That's exactly what happened. Lots of jewel tones and a few browns/sand FQ's. Actually quite happy with it. Not sure I'd do it again though, as now I've got lots of batiks to use up and I don't do pre-cuts as a rule.
