In every envelope

Eight pieces, posted each month

— ✦ —

Six designed pieces, one small painting to collect, and one page from the shelves.

01 · A letter

A letter from the bookshelves,
for anyone obsessed with flowers.

One page, folded into the envelope. Every month, one flower I have been quietly obsessed with — its folklore, its fairy tales, the small things gardeners noticed a century ago, an illustration that made me stop on the page. All of it pulled from the books on my shelves, the same books OBS Books was built around.

Signed and stamped in burgundy ink. Always a little different.

A monthly mail club from OBS Books · Bangkok.

02 · A postcard

A botanical postcard,
written to somewhere else.

A single card with a botanical illustration on the front. Meant for posting — to a friend, a grandmother, or a person you have been meaning to write to.

Yours to keep, or to post.

03 · A bookmark

A bookmark in field-guide style,
a single flower with all its parts.

Each piece shows one flower — bloom, bud, seed pod, stem, stamens — with each part labelled the way the old field guides did it. The Latin name sits at the top.

Printed on cotton rag paper, the same stock as the postcard and the art insert. Soft, textured, the kind that holds watercolour well.

A different flower every issue.

04 · A sticker set

A small set of stickers,
for letters and journals.

Three or four individual die-cut stickers, drawn to match this month's flower — by the same artist as the art insert, so they all belong together. Three or four each issue.

For sealing envelopes, marking pages, or anywhere a small flower belongs.

Matte finish. Meant to be used, not saved.

05 · A print

An art insert,
the painting of the month.

A small square print — for your wall, your desk, or somewhere it will be held.

Printed in Bangkok on cotton rag paper, the weight of a page from a good old book.

Printed in editions. Never reprinted after the month is out.

06 · A stamp

A collectible monthly stamp,
one of twelve this year.

A single gummed stamp, designed in-house and printed once — one for each month of the year, twelve in total, never reprinted.

Some readers frame them. Some use them. Both are right.

First-issue readers receive five bonus stamps with Issue No. 01.

08 · A page from the shelves

A page from the shelves,
the book itself, in your envelope.

An original plate from a flower book on my shelves — or for the rarest, scanned and printed on archival paper. A small slip notes the book, illustrator, and year.

A different page every month. The kind of plate you would frame.

Sourced from the OBS Books archive.
