All you need is ready-to-fold cards (with matching envelopes, unless you wish to make your own), some scrapbooking paper, a pencil, scissors, any stickers/decorations you want, and colorful pens/markers. Most of this you should have around the house, and if you download the JoAnn app, you can get plenty of coupons for JoAnn Fabrics & Crafts. All together, this DIY should be under $30 if you already have the markers, pencil, and scissors on hand. When you put things in perspective, this DIY can save you immense money on your card-buying (I've noticed lately that most cards in stores are at least $4 for a decent design, but often $6-7 each).
First, you'll want to fold your premade card paper together.
Then, decorate the crap out of it! My friend Savannah (from Brewtine) had created these adorable baby onesie cards, so I traced over one in blue paper for a nice template to use as a card cover.
