What you need:
Tissue Paper
Scissors
Marker
Ruler
(Optional): Poster board, wrapping paper, decoupage, and a paint brush
Because I'm lazy, I took a sheet of tissue and folded it the way you see up there. I flipped it horizontally and made marks every 3 inches.
After that, cut the middle of those strips and, voila! You have multiple sheets.
Now, you're pretty much done. You can just stick these sheets in a small envelope and call it a day. But because I love arts and craft, I made my own packaging for these.
Above is a mark-up of the packaging I made. I cut along the outer black lines and then folded by the inner black lines.
After folding it, I cut the wrapping paper to the size of the envelope and glued it using the decoupage.
I let it dry and then stuck my blotting sheets in there. Now, you're done!
Love,
M
