H2H being quilted

I'm having a devil of a time getting this one done. The thread keeps breaking. I've rethreaded, changed the needles twice, next I'm checking the bobbin for near emptiness, and last I'll change spools.
Here's the quilt on the machine.

I'm quilting a zig zag pattern in the rows that parallels the row before. I like the look, but all that pivoting might be the stress on the thread.

Linking up with the H2H site.  Go on over there and look at the other charity entries. It's my favorite charity.

P.S. Happy Mom's Day!

Hugs,

Terri
