Easy to use.
Paper Size: 8.5-x-11-inch
I used this on a vase with a photo of roots. Looked pretty good and I am not crafty. Easy to work with but it did take me two tries as it was my first attempt. All in all a think it worked great. Would definitely recommend.

Good paper.
Size: 13"X19", Size: 13"X19"
First time purchasing A-Sub brand paper & they have a customer for life. I have an epson 8550 & this paper dried soooooo quickly. The glossy finish is amazing, the paper is nice & thick (but not too thick where it can’t bend) & no limit on crafting options. Only thing I did notice is a few of the pages started to ripple or curl not really sure what that’s about. But non the less it’s some really good paper. Will purchase again. Used to make jumbo Valentine’s Day card & it worked perfectly.
