"If you are going to take your precious free time for months and build something, there is no excuse for second-rate work. You cannot claim client deadlines or lousy budget, since you have control over both of them.

"The opportunities to do the great defining pieces of your career come around once every couple of years. Are you going to waste those rare chances on a less-than-grand endeavor?"

Kim’s recommendations

Sculpting supplies

I use "Le Beau Touche" modeling clay from Chavant. This plasticine goes for approximately $4/pound. It is mid-level hardness, formulated for northern climates.

I make molds using these materials from Smooth-On corporation:

Mold Max 30 high-tear-strength silicone rubber
Plasti-Paste Trowelable Plastic
Thi-Vex II Silicone Thickener (thixotropic agent)

My supplier here in Washington state is Far West Materials.

(By the way, Smooth-On's site offers amazing must-see moldmaking video instructions. I wish I'd had these when I was starting out!)

I strengthen the mold rubber by adding small amounts of Fibermesh 150 e3 polypropylene multifilament fiber (often called "stealth fiber"), sold by concrete suppliers . Here in Seattle I use Glacier Northwest.

Glue gun

My hot glue gun, the 3M Scotch-Weld Hot Melt Applicator TC, costs about $100-140 and is well worth it. I’ve burned up seven ordinary $25 glue guns in the past two years. This orange beast can effortlessly put out several pounds of glue a minute. It requires specific shaped glue sticks available in 11-pound boxes. You can find great deals on the web.

Tree textures

Posted by Allen | Technique | Sunday 12 April 2009 1:26 pm

I am determined to make the concrete Tree Troll almost indistinguishable from real wood. To do that, it is important to understand the complex language of surface texture. The whorls, knots, cracks, and crevices that trees gain as they grow are very characteristic.

Each day I mix up a pint batch of mortar and spend about an hour and practicing, using old weathered driftwood as reference. Pictured here are some samples of the real thing, along with some good tests — and some dreadful ones. Another photo after the jump.

It will take about a month to really get a feel for this. At that point I should be able to teach others a simple set of techniques that get good results.
