Step 5: Clamp, measure and bend
Heat up the 1" strip of acrylic with your heat gun, by moving it back and forth along its surface until it visibly starts to droop. The acrylic is now very hot. Put on your oven mitts and bend the acrylic down towards the floor to a 90 degree angle and hold it in place until it starts to cool and maintain this shape on its own. Let go and wait a few more minutes for it to cool more.
