I keep telling myself I need to try neenah paper. I always read such great things about it. I use momento ink, too. I would love to find a blacker black ink that doesn't smear at all, but I haven't found one yet.
I love lots of different brands of stamps as far as images to color. Are you looking for cutesy? These are some of my favorite companies for cutesy stamps: CC Designs, Kraftin' Kimmie Stamps, Wags 'n Whiskers, High Hopes, Pink Cat Studio, Stampavie, The Cat's Pajamas. On my wishlist to try are Whipper Snapper (so cute!), Penny Black (they have lots of cutesy and classic, beautiful images) and Flourishes (their stamps aren't cutesy, but they are gorgeous!).
