Stickers & tabs

Fernwick Stickers

Sticker kits cut to the weekly vertical box

Visit shop ↗
The challenge
Buyers kept trimming general-purpose sticker sheets to fit Hemlock & Oak's weekly vertical columns.
The approach
Fernwick measured each column in B6, A5 and A5+ and redrew their kits around those widths, with full-box, half-box and header sizes.
The product
Three kit families per size, each tested with gel pens and fountain pens on the planner paper before release.

“I stopped cutting stickers in half. They just fit the box, every week.”

Inserts & refills

Larch Lane Paper Co.

Undated dashboards that sit beside your weekly

Visit shop ↗
The challenge
Lifestyle planners wanted goal and project pages without switching to a second notebook.
The approach
Larch Lane matched the paper weight and page trim, so inserts don't stick out past the planner's edge.
The product
Monthly dashboards, project trackers and a yearly review set, sold per size.

Results Sample figures

3×insert sales year over year

“My goals finally live in the same book as my week. Nothing sticks out or curls.”

Journaling supplies

Paperbark Junk Supply

Ephemera for turning a spare notebook into a junk journal

Visit shop ↗
The challenge
Junk journalers wanted to reuse planners and notebooks, but most ephemera packs are too bulky to close the cover.
The approach
Paperbark sorted packs by size and kept pieces thin, so a finished spread still closes flat.
The product
Monthly ephemera drops with vellum, tags and tuck-spots, labelled by the notebook size they suit.

Results Sample figures

2,400kits sold across 14 drops
62%of buyers order again
< 3 mmadded thickness per spread
“My old A5 planners have a second life now. The packs are thin enough that the book still closes.”
Sam K., Junk journaler Sample

Pens & ink

Hollow Pine Ink Lab

Which pens ghost, which bleed, which behave

Visit shop ↗
The challenge
Stationery lovers kept asking the same question in forums: will this ink bleed through?
The approach
Hollow Pine wrote the same test spread with every ink on Heritage 120gsm and Archivist 70gsm, then scored ghosting and bleed.
The product
Swatch cards and a searchable ink list, updated each month, with nib sizes noted.

Results Sample figures

140inks and pens tested

“I check their list before I buy any new ink now. It has saved me a lot of money.”

Inserts & refills

Bramble Ledger

Business inserts for sole traders

Visit shop ↗
The challenge
Small-business owners planned their week in a planner but tracked money in spreadsheets they rarely opened.
The approach
Bramble Ledger built inserts around a monthly money review that takes about fifteen minutes.
The product
Revenue, invoices and content calendar inserts in A5 and B5, with a quarterly summary page.

Results Sample figures

“Invoices, launches and my week are on one desk spread. I actually do the monthly review now.”

Covers & charms

Morrow & Mend Leather

Leather jackets measured to the hardcover

Visit shop ↗
The challenge
Cover makers sized to paper sizes, so jackets for hardcover planners were often too tight.
The approach
Morrow & Mend measured the hardcovers themselves and added a small allowance for spine thickness.
The product
Jackets in B6, A5 and B5 with a pen loop and back pocket, made to order.
