Fold Kids Clothes Into Bundles

I have always folded clothing according to type, pants in a pants drawer, shirts with shirts, etc. Just recently I have begun to fold the kids clothing into "bundles" with shirts, pants, undies and socks, all rolled up into the longest article of clothing. My kids have just 10 bundles each. I try to limit it so that there are no unloved clothing stuffed into the back of drawers.

I know just what the kids need when they outgrow an article (or 2), to make the bundles complete. This saves me money because I know when to stop buying. It also saves me time because the kids know that when there are only 2 left, to tell me so I can do laundry. I only wish I had thought of it 10 years ago!
