Usually to process photos I like, or for clients, using Lightroom. I've also used Picnik for other things, but I just realized you can make photo collages using Picnik! I love this feature, especially for blogging purposes! Hoping to enhance my blog for next year, you'll definitely be seeing more collages on here!
This is also a super-cute idea for Father's Day...which I'm taking to have processed today so I can have it ready for Sunday (can you say LAST MINUTE LARRY?!)
Happy digital collage-ing!
