! Good old !Hi There. I remember having a device before that did the trick. It was almost like a shaver, with round holes that would suck up and cut off the bobbles. It was actually quite effective. I'm not sure where you'll buy one now, but it'd be worth looking in Hickey's, drapery stores or maybe even Argos? Another trick that sometimes works is laying down masking tape and ripping it up, bobbles and all.
