Even if you don't scrapbook , these fun papers come in handy for all sorts of DIY projects from coasters to table numbers. Here are a few of my favorites from Etsy:
These Ink & Elm designs are just plain terrific. The prints are original and cool and the colors on-trend.
Create.Do.Inspire has so many great color palettes with thoughtfully chosen prints, that this is also a great place to get a little color inspiration for your wedding theme.
Perfect Printables is the place to find fun, bright papers! They do whimsy very, very well.
Tracy Ann Digital Art has a ton of selection, but especially for the more traditional wedding. She designs beautiful muted patterns and keeps to an elegant aesthetic.
