These would look darling in a nursery or a craft studio. I know, because I have them up on my wall right now! They depict a sort of "water cycle" for knitting. :) It's raining outside > you make yourself a nice hot cup of tea or coffee > and then it's time to knit!
If you don't have any room on your own walls, they'd make a great last-minute gift for a baby shower (pun intended) or a knitting friend. You could print them out & frame them before you gift them, or for the more tech-savvy, how about putting the files on a pretty flash drive / USB stick? I think that would make such a cool present!
* I couldn't include them all on here, so visit my website to download the prints in pink, and green, as well as the original SVG file if you'd like to alter them.
