(1) So is "bearding" when the batting fibers poke through the outer layers of the quilt? I've never encountered this before, and just recently heard the term. Bearding is more noticeable (1) when the fabric is darker than the batting you are using and (2) the thinner the fabric is. So if you are using darker fabric, use black batting. It may not solve the problem, but it will be less noticeable. It can happen on both the bottom and top of the quilt sandwich.
(2) RE Needles: How can you tell if the needle is dull? Is there any way to SEE that? Or, do you just avoid a dull needly by routinely changing to a new needle after a certain time? Also, I've been using a Schmetz maching quilting 90/10 needle. Is this type/size appropriate? I usually use an 80/12 for piecing/paper piecing and a 90/14 for quilting. I have never seen a 90/10. I use Schmetz needles (because they are easily available) and always use sharps. I never use universal needles. I have heard good things about Organ needles, but haven't bought any yet. I have heard recommendations to change the needle every 8 hours or at the beginning of every project. I agree with others that there is a different sound and feel when the needle needs changing.
