She was kind enough to send me a copy of the stationery, and it’s adorable, with a delicate watercolor-like quality. Check out her other printable stationery sets too. (I’m really partial to the coffee one.)
Incidentally, if you have an Etsy shop or similar where you sell items related to bento, cooking, Japanese/cute culture and so on, you can post a free classified ad  in the forums. I’m really fond of well designed items by independent crafters and designers (anyone making one-of-a-kind furoshiki or bento bags for example?), so if your store or product catches my eye I’ll feature it here on the main site too. If you’re not sure whether your store or product is suitable for this site, just ask me  first.
(Of course, if you have the marketing budget, you can consider buying banner ad space . :))
