A great gift idea! Get a bunch of quotes and color code them based on what they are about. Mod podge a key on the inside of the mason jar, fold the quotes and put them in. Finally, top it off with a cute ribbon and any other decorations you want.
"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
