Uprinting.com has been a sponsor of my blog for some time now and I have been quite pleased with their partnership. I have used their services to create posters and holiday cards. I have found their work to be of high quality and the UPrinting team is a pleasure to work with.
If you have a blog and would like to be a part of the blog sponsorship program, sign up here. You'll be part of a community where you can communicate with other bloggers. You can also host giveaways and receive blogger appreciation prizes.
I currently have three UPrinting giveaways going on at this time. The first giveaway is for a set of 50 custom thank you cards with envelopes. The second giveaway is for a custom 18x24 poster print. The third giveaway is for a custom 16x20 rolled canvas.
