well, truth is, what kind of machine are you using, what kind of thread- what size needle does the machine manufacturer suggest- i use a size 18 on my long arm for coats and clarks star thread, cuz thats the size they told me to use. no problems-
size 16 jeans needle is a heavy needle. it never hurts to arm yourself with as much info as you can, makes you a better quilter.
