I’ve always used floss as the “hair” on the slip d, then tied the hair stop on with a couple of granny knots then blobbed with a lighter.
I then remove that bait and hair stop and discard it, then turn the floss loop so the blob is half way down the loop, then rebait, so the blob ends up in the centre of the boilie, then hair stop as normal.
I do this because when I bait up, then give the bait a quick sniff, I can smell the melting/burning smell left from the blobbing process, but by replacing the bait and positioning the blob in the middle of the bait, this is eradicated. Extremely fussy I know! But it makes me feel happier!
yet when I lasso and blob a pop up using floss, I can’t do that, and catch perfectly well, so the “blobbing burnt smell” can’t be that off putting… 🙄
