For an inexperienced tiler, a kitchen backsplash project is a much better place to start than, say, a shower -- which needs to be waterproof.  Consider these things --

Most splashes cover relatively little area (smaller, manageable project), but have a lot of edges and often incorporate decorative patterns (more cutting).  Almost any kind of tile can be used (fun to design a creative look), but various types of tile can require special types of adhesive, sealant, or grout; and some tiles are more vulnerable to scratching, etc. Some decorative tile will be of different thickness than its neighboring field tile (complicates installation).

Backsplash tile work usually does not need special sub-strate preparation. Most stable surfaces that are clean, dry, and relatively smooth will work.  (...much less rigorous substrate requirements than wet-wall or floor tiling.)

Don't forget that you will need to cut/fit tile around outlets and switches. Remember these also when planning your tile lay-out.

SITK staff can be helpful as you select tile and think-through installation rerquirements. Our annual odds & ends sale each fall is a good place to pick up smaller quantities of cool tile types, colors, materials.  ...and we now and then offer do-it-yourself how-to seminars on various kitchen-bath topics, including tile work.
