Follow the links in the header for specific terrain making projects.More to come, but here are some links for now:

Terrain Making Sites

• TerraGenesis - "The web site devoted to the production of terrain for table-top wargames. Our aim is to show you all you need to know to make great looking, cheap terrain." Need I say more? They have lots of cool stuff, but one page you might overlook is their Bits & Pieces page, which is quite cool. If only I had read this site earlier! They have just about every cool thing I have found. I was so excited at having discovered ceramic tile spacers, but it's old news to them.
• Gaming Scenery Page - A site for a colonial war gaming fan, but it has some nice, well communicated and generally useful tips as well.
• Lloydian Modelling Tips - Neat site, especially his Scenery page.
• WorldMakers  Helpful instructions and illustrations.
• Starship gaming terrain - this fellow made a very inexpensive board and scratch built miniatures.
• Necromundicon (Sean Patten's Site) - I ahve only just heard about this, but it looks good.
• Net Terrain - lots of guides on building various terrain pieces.

Foam Cutter Vendors

• Hot Wire Foam Factory - Oh my, they have cool stuff! I have their Foam Factory. Look what I did with the scroll table!
• Avalon - Seemingly the most popular choice for hobbyists after the el-cheapo Wonder Cutter.
• Croma - Professional tools for foam cutting. They are expensive, but look very good.

• Hirst Arts
• Linka

Terrain Kit Vendors

• Monolith Designs - Highlights - ancient Egypt, darkest Africa, and Aztec terrain.
