Has anyone had problems with the sporran causing "wear" on the front of a PV or wool kilt? I noticed on my PV kilt that where the Sporran hung is a little different texture now... kinda like a well worn sweater, kinda has the fuzzies! is this common? Is this caused by a cheap sporran (which I admittedly have)?

I'm kinda hesitant to wear my sporran with my new wool kilt if it's going to do the same thing!
