To make your own scratch off tickets you'll need;
dish soap (any brand should do, but if you're curious I'm using Ajax)
acrylic paint (any color and brand of your choice)
2 // Grab a piece of scrap paper and tape down the card you're wanting to put the scratch off area on - making sure to cover the whole area you want painted over with tape.
3 // With painters tape, mark off what you don't want painted over. If you're brave and have a steady hand you could skip this step but I definitely prefer the clean lines that painters tape gives me.
4 // Paint! Use thin, even layers. Don't worry if you can still see through it after the first coat, it will most likely take two or three coats to get it all covered.
5 // After the paint is thoroughly dry, carefully peel off your painters tape. Go slowly so you don't accidentally rip off any of the paint.
6 // Cut the cards off of your scrap paper and TA-DA - you've got pretty scratch off cards!
Make sure to send me pictures if you make some too! I'd love to see them.
