One of the seals simply has my name, Cathy, in katakana - i.e. Kyashi = キャシー. The other has a pair of kanji representing the sounds "ka" and "shi". Of course, there are numerous possible pairs of kanji that have those particular sounds associated with them, so I had a choice. The shortlist came down to: 佳志 (roughly, "great faith") and 果詩 ("fruit poetry"). Naturally I chose the latter.
If for some reason you wish to know much, much more about name seals, you find out here. Meanwhile, I'm very pleased with mine!
