Use a gluestick, and when the need to clean the block arises, just lick it clean.
OK, I'll go to my room now.
And you're right.
There is a learning curve associated with spun bodies. I have dabbled with blocks off and on that I have crafted (BOY, is that stretching it!) from wood scraps, etc. But have mostly used the drop loop method. I find it is so much easier to come up with consistent bodies on a block because of more control with the dubbing placement. I'm trying to learn how to combine the abdomen and thorax in one loop now.
