I use photoshop for all my work. The center line is three bubbles to start and the way photoshop works is the top of one bubble snaps to the bottom of the other and the other two snap to the center where the others join (hope that makes sense). Then I just repeat this for the other rows . The the rows won't snap to each other so its by eye with careful nudges. This is actualy not perfectly aligned but its pretty close. Thanks very much for the compliment! I aim to improve all the time.
it's a an awesome book. i like the young lady's primer even better. i started the three book cycle of course i can't remember now, it was historical fiction, i really like that one too. i expect you like wiliam gibson and such like?
I believe that series was The Baroque Cycle though I've never read it myself. Its been ages since I've read anything by Gibson too, I haven't dipped into good Sci-Fi in a long while! If I get all the alignments working on the other bubble image I'll post it up
