a way to use large spool of thread on a standard machine. set the spool in a heavy cup and bring the thread around the spool pin so it makes a 90 degree turn to the thread guide. Set the cup directly under the spool pin.
Double needle (or straight wound) if don't have upright spool holder, tape dowel rod to end of machine. Put on a spool to add height, then the spool you want to use. or a wound bobbin if doing double needle and don't have second spool of that color.
Using the Double Needle, WITHOUT the 2nd spool holder
Love the comment from other pinner, "How to use a double needle tutorial.shut up! This is amazing. I learn new sewing stuff all the time!" The other thing I didn't know is the double needle seam stretches.
