HQ Conductive thread (from Mitsufuji)
10 yards, 8 ohms/foot
Conductive thread is flexible and washable like regular thread, but also conducts electricity like a wire. Made from thin strands of spun silver.
We have tested many different kinds of conductive threads and our favorite is the high-quality thread from Mitsufuji, which is such a joy to work with.
It's a thin four ply, highly conductive, and less prone to corrosion and fraying. We're currently experimenting with dyeing it to better fit your palette. See our analysis and comparisons of conductive threads.

Conductive thread (from Shieldex)
10 yards, 20 ohms/foot
Our second favorite is this 2-ply thread from Shieldex, also spun silver on a nylon base. It works pretty well, and has been our mainstay for the past couple of years.
Unlike the Mitsufuji, this thread is a dull gray, is harder to dye, and has a tendency to fray. All thread loses loses a bit of conductivity every time it's washed (until it eventually doesn't work), but this thread loses conductivity faster.

Conductive paint
0.10 Ohm/square at 2 mil dry film thickness
Copper-based conductive paint is a wonderful way to make electrical connections on paper, walls, or ceramics. You just have to paint the electrical connections, and wait for it to dry.
We use the CuPro-Cote from LessEMF.

Conductive fabric
3x3 square inches, 1 ohm/square
The light gray conductive fabric is also flexible and washable, but it is also very conductive, and can carry a lot of current. Use it for making switches and touch-sensitive pads by connecting it to the touch switch.
In the remote control project, it's used for the Forward/Volume UP actions. Made from silver coated nylon.
Also, instead of sewing a long stretch of conductive thread, you can iron this unto some fabric with some adhesive backing. We typically sell this in squares, but can accomodate other sizes, just ask.

Resistive fabric
3x3 square inches, 30 kilo ohms/square
The darker, resistive fabric is not so conductive, and we use it with the custom sensor for projects that need a change in resistance, like a pressure or stretch sensor.
In the remote control project, it's used for the Back/Volume DOWN actions. Made from carbon impregnated polyethylene film.
This is plastic, so it cannot be ironed! Again, we typically sell this in squares, but can accomodate other sizes, just ask.
