Even though we have tried to get rid of a lot of outgrown clothes, we still have quite a few boxes of things we need to keep until we are done having children (we keep gender-neutral PJ's, winter coats, pre-walker shoes that show very little wear, clothes homemade by my Mom and me, etc). Plus there's boxes with clothes I have bought ahead for next season, plus a box of clothes from last season that I have to hang onto in case some of them still fit the following year. I am using those clear Sterilite boxes. I know it's been mentioned before, about clothes starting to yellow after being stored for a while. I've had this happen before, to some of dd's newborn clothes (which is what prompted me to start giving away stuff rather than keeping it). So far the rest of the stuff is okay, but I was wondering if even cardboard would be better since it's not airtight. Or does that just introduce other problems?
I can't really afford expensive storage solutions but was wondering if there's an alternative to what I'm doing that might help the clothes last longer.
