I got two stamps for texturing walls from MiniWorlds a italian company and a template for roman doors and windows. The two wall texturing stamps are only two examples there are many more on their web page.
Here is the first one: The MT 009 San marino type
This stamp is to be placed on a piece of Styrodure and pressed into it to imprint the stone layout into the Styrodure. You will get this:
Depending on the stability of the Styrodure, there are different grades of toughness, you might need a hammer to make this work ( like shown on the companies website. It took less then 5 minutes to do this. Doing the engraving by hand would take considerably longer.
Next up is the MT013 Siviglia type:
This is what you get after using :
Both stamps can be joint to produce bigger ares of stone on the Styrodure , just align them properly.
What I got too is a product called minimask. A stencil template to do roman arched windows and doors . Also from MiniWorlds. You use this to draw window and doors onto the Styrodure to cut them out later. One word of warning though the one I got was very fragile.
This is MM001 roman arches:
Excuse the bad picture . Better ones are on the companies website .
When you place them on the Styrodur you van use the one cm lines on the template to align them properly.
Here is what you get when you use both devices :
And together with the other template:
All in all a very good product . Recommended but using a hammer is necessary.
I will use these to build some buildings in the future so watch this space.
