Don't you hate it when the waist elastic in the back of a garment twists!!! I have a pair of tracksuit pants, that I purchased because they looked lovely and thick.

The problem could have easily been prevented if the manufacturer had added one or two tiny steps when they were being sewn.
This tutorial will show you two easy techniques to stop waist elastic from twisting.
