There's no one answer to this question; each clay brand has its own strengths and weaknesses, and different clay artists have different preferences. Some of the available brands are:
The best brand for you will depend on what you want to use it for, and also on your personal preferences and how you like to work with with the clay. The Polymer Clay Central FAQ includes a comparison of clay brands; so does the Grin and Bear It Clay Art page. Some of the clays are available in sample packs that let you try several colors in small amounts. You can also mix different brands of clay to get the level of softness, color, and other qualities you want.
For making beads or covering objects, any of the polymer clay brands will do fine. However, if you're making objects (such as boxes, picture frames, etc) from clay, or creating buttons or thin pieces that must hold up to handling, you'll want to select a strong clay such as Fimo, Promat, or Cernit. If you want to use a weaker clay such as Sculpey for such pieces, first make the base piece from a strong clay, then apply the weaker clay as a veneer over it.
There's no problem with mixing different brands together, and you may want to do this often to obtain the properties of both clays. For example, many clayworkers mix Sculpey with Fimo to get a clay that's easier to work than Fimo, but stronger than Sculpey. You mix clay simply by conditioning the two kinds together, or by working conditioned clay until it's thoroughly blended.
This depends on your personal preferences, but there are a few guidelines that will help when you're making canes. Finely detailed canework depends on contrast between the parts of the design, so place light clays next to dark ones. Often, the impact of a piece is increased when you use related colors - for example, a warm orange-yellow with a warm dark brown, or a series of shades of cool blue. Metallic clays used with black create a striking effect. Try different combinations - the same design can look completely different when made with a different set of colors.
If you want to use two clays of about the same lightness in a cane - for example, a pink with a yellow - try wrapping one or both with a thin sheet of a contrasting dark color, such as black or navy blue. When the cane is reduced, this sheet will become a very thin layer that will help set off the pink from the yellow parts of your design.
(Fimo burgundy has been known to sometimes bleed into lighter colors after firing, so avoid placing this color next to a light one.)
You may be perfectly happy with clay right out of the package; Fimo in particular comes in some beautiful colors. However, sometimes you can't find just the right color in the clay brand you want to use. Here are some tips for mixing colors:
Remember to start with the main color and mix in small amounts, gradually, to avoid going too far - for example, to make a translucent red, start with a lot of translucent and mix in small amounts of your red until you get the effect you want.
When two colors of clay are thoroughly mixed, the distinction between them disappears. However, if you stop the mixing partway, you'll get a streaked effect similar to marble. (Make sure not to stop mixing in time to preserve the marbled grain you want; continued handling of the clay will mix it further.)
Different color combinations can give you the effect of various semi-precious stones: for example, marbling several shades of green with white produces a clay that looks like malachite. Marbling earth tones and translucent gives the effect of agate. Pearl white with small amounts of dark gray and translucent makes a good marble.
You can vary the marble effect by mixing the clay in different ways. Roll the partially-mixed clay out into a thin snake, or pull it, to obtain narrow streaks. Running it through a pasta machine one or more times produces a different sort of streaking. Repeatedly twisting and folding the partially-mixed clay strands can make an effect like natural amber. Once you learn how to marble the clay, try different techniques at different points in the mixing for subtly different effects.
You can roll out the marbled clay and use it to make (or cover) flat items such as boxes and frames, or roll small bits of the clay to use as beads. Large marbled beads are especially effective. You can also use marbled clay as part of a cane design.
Many clay artists use continuous shades of a single color, from light to dark; the work of City Zen Cane in particular makes much use of this technique. One method of obtaining such a gradient is simply to mix seven or eight shades by combining the base color with different amounts of white, then flatten each shade into a sheet and stack the sheets in order from dark to light.
An easier method
for mixing a gradient has been described by Judith Skinner: you make
a triangle of white and a triangle of the color you want to blend, put
the long sides together to make a rectangle, and run this sheet repeatedly
through the pasta machine, folding it in half each time, until the colors
are blended together. You can use this same technique to blend two colors,
or even use several tall triangles (instead of just two) to create a multi-color
