Inventory 01–03

Three divisions, one eye for useful things

The divisions deal in different materials, but they share the same test: is it well made, useful, instructive, or strange enough to keep?

Why these things belong together

Not everything needs to be new. Not everything old is automatically valuable. Johnny's Mercantile looks for what is well made, usable, instructive, or strange enough to preserve. Sometimes that is an old leather jacket. Sometimes it is a forgotten construction method. Sometimes it is a historic object that can be made again with modern tools.

Vintage

Leather clothing

Motorcycle, work and alternative leather selected by material, construction, wear and repairability.

Vintage

Boots & functional wear

Used goods are measured and described as they are, including marks worth knowing about.

Digital PDF

Leather drafting guides

Guides for hats, bags, armour and other projects, built around measurement rather than fixed sizing.

Physical object

3D-printed curiosities

Decorative busts, anatomical forms and historically minded objects.

Digital STL

Printable models

Downloadable model files for people who own or use a 3D printer.

PDF + EPUB

Historical Editions

Clearly separated digital editions of selected public-domain texts.

Working method

Find, examine, make or describe, trade

The object changes. The habit of looking closely does not.

  1. Find

    Source a useful object, method or subject instead of filling a catalogue for its own sake.

  2. Examine

    Check material, construction, measurements, condition or historical context.

  3. Make or describe

    Produce the object, prepare the file, or explain the method without hiding the limitations.

  4. Trade

    Direct the buyer to the appropriate public platform, where the actual transaction takes place.

Field notes

Practical reading

Three short articles on mistakes that cost more than a few minutes of thought.

NOTE 01

Why a card mock-up costs less than ruined leather

Card exposes proportion and movement errors while they are still cheap to correct.

NOTE 02

Why vintage size labels are not enough

Old labels, changing standards and altered garments make actual measurements essential.

NOTE 03

Physical 3D print or digital STL?

One arrives as an object. The other is a file and a printing job still to be done.
