=20
thanks, Len!!
most welcome! i apologize for making more changes than needed.
be better teaching to just do the minimum needed
=20
I, too, suspected the multiple leads to be a problem...in the future I
will definitely try harder to set my lines to a width that actually
exists.
when i have to use two leads 'stead on one, i try to get lengths about
two-third and one-third, and alternate the breaks from one side to another
much better than halves, which lines the breaks line up, up the middle
of the block
i also try and distribute the full width single leads throughout the
block
=20
I didn't know we had blue paper spacers! cool.
except they expand when they get solvent on them.
i use them rarely and as a last resort
=20
thank you x 1000!!
-Kristin
have fun finishing the job
