A couple years back I tried going back and forth on builds- 4 or 5 at a time- then last year went back to focusing on one build- and it is actually getting done! I will then go to the next one in line, finish it, then move on again........ I do more scratch building and trying things I wouldn't have dared attempt years ago- sandwiching styrene stock together with white glue, shaping, then soaking the stock apart- modifying a part into something completely different- cutting cedar cigar wrapper into strips using a jig, for boat planking- will soon be attempting resin casting from rubber molds, and finally using an airbrush (need to get a compressor). Molotow pens are a godsend.
