Start by covering the glasses you are going to use with plastic wrap.
Pour the Stiffy into a disposable bowl. NOTE: You can pour any excess at the end back into your container and reuse it.
Add your doily to the Stiffy and be sure to cover it completely.
Then squeeze any excess from the doily. IMPORTANT: You do not want to wring out your doily as that may stretch it.
Apply the doily to the bottom of the glass. Press the bottom to ensure it is flat.
Then create pleats all around the outer edge to take up the excess material.
Once happy with the shape, set aside to dry overnight.
Then just remove from your glass and your doily tea light holders are complete.
