Did you know you can use your serger to gather fabric? Imagine the possibilities ~ no more knotted or broken threads when you gather fabric.
Set your serger for 4-thread serging.
Increase your Differential Feed to the highest number ~ (this machine the highest is 2)
Increase your Stitch Length to the highest number ~ (this machine is a 4, but some sergers go up to 5.)
Serge along the raw edge. You will notice that it does a little gathering. This is normal.
Notice the two needle threads (the black threads). Near the fabric edge, put a needle underneath the two parallel threads. Be sure not to catch either of the looper threads ~ it will knot if you do. Just the needle threads.
Pull the two needle threads out of the chain of threads. Do not let these get tangled. If you do this correctly, they will slip out easily.
Pull the two needle threads to gather your fabric.
Voila! You will have a nice and even gathers that can easily be adjusted and then attached. No, stray threads that end up on the outside of your project.
