To initially gain skill it might be best to start with making iron bowls. Granted they're not worth much to traders and are useless except in altars, but since each bowl is 0.3 kg, they don't use that much lump and they're made from a readily-available substance (iron). The exception to this is if you have access to a vein of gold or silver, in which case rings are the better choice, both in terms of value and lump consumed.
