I'm doing my first drywall taping, and I need some advice. I did a "test
strip" on one seam, using the perforated tape which the instructions say to
put down on the dry seam, then cover with a coat of mud, pushing the mud
through the perforations.

Now I have a couple of spots with bubbles in the tape, and there is a
"bubble" down the one entire edge of the tape. In other words, this isn't
going so well.

Two questions:

1. How do I fix what I've done so far?

2. How do I avoid this the next time?

Thanks!

I've had better luck with the plain old paper tape. The perforated
stuff is usually thicker. OK for where the factory edges meet because
it's buried in the bevel, but when you get a cut edge or a corner, it's
harder to feather it out.

Fixing it??? Rip it out (GENTLY) and start over. It's good that you
have a practice joint.
