tapestry, or just paint the wall behind you
green? just wondered if there is a specific

used in order to acheive desired effect?
You can leave an optional "tip" with Mahalo's virtual currency, Mahalo Dollars. If you are asking a difficult question that might require some research, or if you'd like a wide variety of feedback, a higher tip often leads to more answers to your question.

For large jobs, use the mixing instructions, and for small stuff use the spray can. Flat paint is essential, as you need to diffuse specular light sources (point light sources like the sun or clear light bulbs). Gloss will create glare, and glare is the enemy of chroma key operations.
You might also consider using bluescreen instead of greenscreen, and there's a link for the inexpensive option:

And as far as the blue vs. green debate goes, you can check out:

Long story short, green is best for most things, unless the subject is wearing green or a prop colored green.
I am curious as to what you are cooking up! I have occasionally done weather casts on a bluescreen. Hope this helps.

If you are planning to do a lot of green screen work you should get a muslin green screen. I have had good experience with http://tubetape.net. They have kits with lights, the backdrop and software backgrounds that can be pretty handy if you are just getting started.
If you have the space for a dedicated shooting area you can get green paint specifically for this purpose. With paint you need to make sure you get flat paint to minimize glare.
