"52 Things I Love About You" Make a table on Microsoft Word, find a cute font, type your 52 things up and print on card stock. I used scrapbooking tape to stick the card stock onto the playing card then laminated the cards and cut them out, ending with punching a hole in each card and tying together with ribbons. *DO NOT mod podge the cards! They will end up sticking together and it'll make a big mess and you won't be able to pull the cards apart--I learned this the hard way
A rope bracelet - reminds me of making friendship bracelets back in the day. My right second toe used to go numb because I'd hook the end of the bracelet over it, and then knot embroidery floss for HOURS.
