To creat the perfect patterns and tooling my first prototype/test build is done in copper. This one is destined to be destroyed as part of the process. #jeffdeboer #mouse #mousearmour #mouseart #mousearmy

Every 16th Century mouse I make has custom hand chased artwork in the ears. It’s a very small canvas indeed. #jeffdeboer #mouseartist #mousearmour #catandmouse #chasingandrepousse

Monday is make a new stake day for the Henry VIII mouse or “Fat Henry” project as will be the title. #jeffdeboer #henryviii #jewellerytools #metalshaping #mousearmour

Step one when building a suit of armour for Henry VIII mouse, make sure you can make the trim because you’re going to need a lot of it, especially around the waist! #jeffdeboer #henryviii #mouse #mouseart #mousearmour

Today is a big day for me—I’m going to start the 40th Anniversary Mouse! It’s going to be the famous suit of tournament armour worn by Henry VIII around 1540. I am only going to make 12, as is usual for my editions. I am asking $6,000.00 in Canadian funds for one.

Another day another 16th Century mouse. I know this is not an in-depth demo of riveting I’m just sharing my day. #jeffdeboer #mousearmour #rivetedjewelry #miniatureartist #metalarts

It’s become a thing for me to setup and take a shot of my process on every project. There might be a book or a calendar one day. #jeffdeboer #metalarts #jewellery #catandmouse #mousearmour

The week ends with a successful build and proof of sizing prototypes for the articulating ring project! If I am going to offer this for sale I still have some number crunching to do. #jeffdeboer #kineticjewellery #armourring #gothicjewellery #gothicstyle

Part of my 40th anniversary year I’m playing with one of my bucket list projects a proper armour articulating ring. If this becomes available it will be sold through my jewellery company armet.ca #jeffdeboer #articulatingring #kineticjewelry #gothicjewellery #gothicstyle

I had four of my 16th century mice completed on Friday, this is my only chance to take a group shot before they get shipped to the collectors. One has to take the time to do this right because one day this image will be in that book or puzzle or calendar I really need to do.

A quick thing on taking photos of my mice. I forgot to mention that black velvet turns the background’s jet black. #jeffdeboer #mousearmour #catandmouse #tabletopphotography #gothicsteampunk

One might think my work as being a miniaturist when in fact it’s actually life size. #jeffdeboer #mice #mouseears #mousearmour #chasingandrepousse

When you hand chase a tiny dragon design in brass for an ear for mouse armour, you push the limits of your magnify glasses and the focus of your phone camera. I had to include a Canadian quarter and my fingers for scale. The tools are equally tiny and dedicated to this scale.

There is an order to things and you have to first do the things you need to do before you can do the thing you want to do. #jeffdeboer #mousearmour #catandmouse #smallsculpture #miniature

Going for a bit of drama in my documentation photo of this stage of production of the 16th century mice project. If anyone is interested in owning one of these there is still one available from this production. I am asking $4,500.00 in Canadian funds for one. #jeffdebeor #mouse #metalarts

Today I finished the prototype 16th century mouse that is going to be on exhibition at the Kunstsammlungen der Veste Coburg for two years! This museum is a German castle that has one of the best preserved armour collections from the period. I am doing an edition of 12 if you’re interested in one.
