WonderFil DecoBob 80wt – Diana's recommended thread of choice.
 
WonderFil’s DecoBob 80wt is an exceptionally fine, smooth, and strong Cottonized polyester thread.  I use it the BAQ studio as my top thread and bobbin thread in the BAQ blocks and projects. It gives the  cleanest possible run‑stitches. Its thin profile gives BAQ blocks a refined, polished finish and helps every line of stitching land exactly where it should.
 
Because it’s so thin, DecoBob creates:
cleaner stitch formation
less bulk in seams
flatter blocks
tighter points
fewer thread breaks
beautifully consistent results 
It’s a premium option for all of your Build A Quilt needs.
