Sorry about the confusing title. I really have no excuse.
So, perhaps the single most beautiful piece of stationery I have ever come across is finally available for purchase. f,l,o,w,e,r,s (16,800 yen) by Norihiko Terayama of Studio Note is an acrylic ruler with embedded real flowers that are “blossoming” at exactly 1cm intervals. Each flower was hand-picked and dried by the designer, therefore making each ruler unique. Absolutely stunning. You can purchase it in Japan or abroad.

Here’s another great find from kami no kousakujo, and a fun little project for you and your toddler. The Kotori Mobile (1,260 yen) is  a paper mobile (even the string is made from paper) that you assemble yourself and is a great way to learn about the concept of balance. Your order will come with 2 sets but the mobile is infinitely customizable. You can add as many sets as you like and because it’s made from paper you can even draw pictures on it, like a forest for your kotori (baby birds) to live in.

It was designed by passkey design, who you may be familiar with via their animal rubber bands.
