I agree. That's why I won't even bloom the ends of mine, although I've had a fair amount slip out even after securing with Tulip. I guess I may have to switch to Elmer's as it seems like that is what many of you guys are using.
Gotta say I'm envious of how you guys keep you FO strands so neatly collected. I going off small (6") spools and the fibers have a very tight curl once I cut off a strand. Trying to corral 30 strands into a neat bunch is frustrating as hell. That's where I get most of the slip thru too.
Right now I'm going with 30 cm length for just about every section. I know I'll be wasting a fair amount, but since I don't know what exactly I'll need for any given section, I want as much flexibility as possible in being able to join various bunches together to utilize less LEDs. Right now I'm figuring six LEDs for all the FO, with the engines and bay lights on a separate circuit.
