At first, mounting a bait on a hair and then securing it with a bollie stop, held many a fear for me. You need to hold the stop in place, hold the hook-length, and then slide the bait up the hair - and by my count that makes three hands required
However, this may help:
Don't cut your bollie stop from the length of plastic that holds them all together. Put the first stop on the strip into the hair. You then have the rest of the strip to hold on to - either with a handy finger, or your teeth.
I have found that this makes things significantly easier.
Also, if you run out of stops, use a thick piece of grass instead!!
