I wanted to share with you guys how I like to store my plastic bags. When I have way too many bags, I like to fold the bags into little compact triangles like this. Obviously this isn't practical when I need to find bags of specific size, so I only fold bags that I have no room for.
To make your own little compact triangle, simply flatten your plastic bag and fold it into a ruler shape (going lengthwise). Then fold triangles up from the bottom towards the bag handles at the top. Once you get near the top, tuck the bag handles into the slit made while folding triangles.
