Here are the directions (copied from Aylee's site, originally from Marthastewart.com):
1 8.5x11 paper
ruler, computer, printer
Using the Word template below, connect the crop marks on the sides with a ruler and fold the paper with the ruler as a guide. Fold solid crop marks towards you and fold dashed crops marks away from you. Center a tissue on the sheet and fold back the sides where the tissue ends. In the back, weave the flaps into one another. Insert tissues in the front. There are pictures on Aylee's site of how to weave the flaps together, or see the attached Word document- basically you just alternate them into eachother in the back.
When I made mine, I used a little heavier paper- not quite cardstock, but a heavy shiny striped paper. The side that folded over was plain, so I used my Fiskars Texture Plate to emboss the filigree design there. I then printed one of my monograms from Creative Montage onto Avery clear stickers, cut it out and stuck it to the front. I'm trying to think of something to put on the back- maybe "To dry your tears of joy...". Is that stupid or cute? I can't decide, so go ahead and be brutally honest.
My brother and dad are singing a song together (and my dad's playing the guitar) during my ceremony, and I know there will be some tears, so I thought I'd go ahead and supply the tissues! lol
