I made myself some wordsearch wrapping paper this week. Basically I setup an A3 word document, created a table that covered the whole page and then added a letter to each cell of the table. I repeated 'happy' and birthday' throughout the paper so they'd always be some to circle however i wrapped the present. Then i printed it on my A3 printer, wrapped the present, finally found the best happy and birthday and circled them in marker pen.
I love how it turned out, cant wait to give someone a gift wrapped in it. Definitely going to use it at Christmas as well.
