who makes patchwork leather cover w customization?

i once saw a small business- i believe it was japanese with an english website- that sells leather covers for hobonichi. i remember a very unique patchwork cover w many colors, like a quilt. there were options to customize the interior of the cover

i believe the creator may be japanese, not sure. his website included video and images of him making the leather covers in his studio. he may be a former clothing designer who switched to making these leather covers?

the name of the business was playful, maybe inspired by an animal

if you can help me find this needle in a haystack, i will be grateful!
