Best needle and thread for machine applique.
 

I need to do a lot of button hole stitch on a wall hanging and I want it to turn out nice. What weight thread and what needle should I use? Thanks in advance.:thumbup:

It depends if you want your buttonhole stitch to stand out or blend in. Black cotton Sulky 30 weight is nice for standing out. If you want it to blend- 50 weight Aurifil that matches your appliqué. Change it each time you get to a new fabric. A topstitch needle or microtex needle is nice.

I use a blind hemstitch rather than a button hole stitch for invisible machine applique. My current favorite is Bottom Line thread (a 60wt polyester) and a size 70 Microtex needle. This is the finest needle available and the sharp Microtex point creates the smallest holes.

I would definitely practice on a fabric scrap or two with several different threads to get the look you want.

I am currently working on a fusible applique project with a blanket stitch (also sometimes referred to as a buttonhole stitch). I am using Wonderfil's Decobob, an 80 wt poly and it is really working well. The stitches are not obvious at all.
