if you don't have anything to collect the resin with, here is what I just did: take a cigarette, empty out some of the tobacco and cut a strip of the paper out. Split this strip into small squares and roll them around the tip of whatever scraper you are using. Once this is done you simply scrape the inside of your whip until the paper is covered in resin.
If you take the paper off and unfold it, then fold the clean side back onto your scraper, you can make the most of the surface area each square potentially has.

Just blaze.
