I’ve heard it a million times – “I want an all metal, vintage machine, but I HAVE to have a free arm so that I can hem pants.”
Really? It’s simple to hem jeans or any other pant leg on a flat bed sewing machine. So much so that I don’t use the free arm for this, even on machine that have a free arm.
What’s the “secret”?
Just sew on the INSIDE of the tube rather than the outside.
Before you start sewing, press the hem with a hot iron and lots of steam. At the bulky seams, either pinch the fabric with a pair of pliers or give it a few good whacks with a hammer.
This will flatten out the “hump” somewhat and make it easier to feed evenly. It’s also important to use the right needle for the job.
I suggest a denim or sharp point needle in size 14, 16 or 18, depending upon how heavy the denim is and the thickness of the thread being used. I’m using a thicker, topstiching thread, so I opted for a #18 denim point.
Here are some more tips for sewing over the “hump”
Keeping the foot level allows the fabric to feed evenly and prevents the dreaded “jam-up”. This is when the foot won’t go over the hump.
