My first sewing job didn't hold well enough.
Take duct tape and squish it onto the fabric
REALLY well. Then sew through it.
I colored mine black to stand out less.
It is SO strong when I was trying how tough it was,
the duct tape and stitches held great, but another
part ripped lol!
You can't tell on the front of
the boots and they're still fine! :)
