I looked up how to make the scratch off part because using a crayon wasn't that cute and I found this helpful idea from ArtMind. I didn't have contact paper but I had iron on vinyl so I used that instead and I used a wide paint brush to put one stroke of the dishsoap/paint mixture across the items all at once. I had to put 2-3 coats on each.
For a baby girl, tie a knot in some ribbon, use a lighter on the edges, hot glue it just under the baby's hair and glue it to some cute pink cardstock and you're all set! Don't forget to bring pennies for the guests to use to scratch it off.
My dear sweet friend was nice enough to help me put these together because I of course did them at the last minute and needed extra hands big time - thank you so much Debs! They turned out great!
