Hi Sarah and Charlie. My apologies for the delay. I got a whole bunch of things going and lost my internet, due to ice. Spent the week catching up. I've add 6 of my favorites from last year's Sleigh Day. They are proofs, only, and will get more attention, as a higher resolution file. They have the 2026 pricing, which will, basically, be the same but, new items have been added.
I'm not sure what she (niece?) has planned but, if she is going to print at 5x7 or less, the medium resolution will be fine. If it's larger than that, you may need the high res image.
Feel free to contact me if you have any questions.
