Back in 1999, inspired by a photo-story in Janus magazine (#38, I think, but I could be wrong) starring Paula Meadows, I made an improvised flogger out of a length of white two-core electrical cable, repeatedly doubled over on itself and then bound at one end with black tape to make a handle.
If I remember correctly there were eight loops in all, so sixteen strands, about 40-50cm in length. I'm not sure if I ever felt it myself, but my then-girlfriend absolutely adored it!
I'm not sure what happened to it in the end; I had it for many years, but I think it must have got buried in storage during a house move and then never seen again.
Although I now have three different suede floggers, I still think about making another one sometime; it's quite a different sensation I think.
