Take the sellotape and place it over your aperture opening—on the inside of the card. I didn't have sellotape that was large enough to cover the aperture so I used three strips and made sure to slightly over lap them so that there was no gap between the strips. You will now have your window covered—with the stick side of the tape on the outside of the card. Step 2 Turn the card over so that you can see the front. You will now put your glitter over this sticky tape. Make sure to cover it well. I used a white glitter to give a frosted effect to my window.
Step 3 Shake off the excess glitter. Make sure to do this over a sheet of paper so that you can save the excess. Make sure to tap the back of the tape to shake off all the excess glitter. 44
