Is it so important that they have to be blue??
And seeing as I couldn't find any blue paper doilies, I dyed my own - and it was worth it!
It's actually really easy!
I had an old metal pan lying around, the kind you buy for picnics and whatnot...
Put just enough water to cover the doilies, and put a ton of food coloring in it.
I mean a ton.
Let them soak for about 30 seconds, make sure to flip them once.
Take them out, pat dry with a paper towel, then set them out to dry
You will need at least one roll of paper towels!!!
They turned out great!
