i also am working on some simple packaging for my books. the small sleeve is a neutral color, since the books themselves are so bright and colorful. i ordered some japanese masking tape to add to the packaging and i'm really excited about it! if you haven't heard of japanese masking tape, take a look at this site. (it's mostly in japanese.) the tape is made by an 80+ year old japanese company that originally started producing fly paper. by popular customer demand, they created a ton of bright festive colored masking tape from japanese paper. it's a bit transparent and is apparently a favorite among artists. i'm looking forward to receiving my order soon! below is a pic of the current packaging idea. i am planning to put strips of colored tape behind the info sticker to make it pop!
sorry it's a little blurry - it was taken with my phone
thats all for now. if you have any comments or suggestions on the packaging, please feel free to tell me!
