For my prints, I love the 8.5x11" size for the versatility.
It can be trimmed to fit in an 8x10" frame, or better yet, fits perfectly (I own a few) in a NYTTJA Ikea frame (comes in many colors), or in a certificate/document style frame (most brands have this option in any store that sells frames), and lastly can be placed in a 'floating frame', or a larger frame (11x14" is popular) with a mat that has an 8x10" opening (easy to find in any print/art shop) for the print image.
You can also have it stretched onto canvas by el and coated with uv protective gloss. The print would in this case, be printed on heavyweight archival canvas and assembled by el.
For more info on the cost and the process you can go to the 'canvas print options' section of the shop here http://www.etsy.com/shop/elloh?section_id=5873218 for the listings.
The limited edition print (100 prints will be made) is signed, numbered and titled on the back (let me know if you'd like it signed, numbered and titled on the bottom front of the print) and comes carefully packaged along with a paper certifying it as an authentic elloh piece-all ready to give as a gift.
The elloh logo is not covering or on the actual print
