I'm trying to model telephone poles on my HO layout. The poles and lights have been completed and I'm now trying to install the power lines at the top of the poles. I tried using some heavy (coat thread) black thread but I could not get the lines (there will be a total of 6 lines from pole to pole) to hang in consistant manner. I'm trying to simulate the caternary found in the full size version. Has any one got any suggestions on a different material. Would appreciate any help I can get.
