Bias Tape is NOT hard to make, you will need
2 Straight Pins
1 Piece of fabric cut 1" x 3" approx - Holding Strip
The strip you will make into bias tape, I cut mine large to show, normal cut will be
3/4" to 1 1/4" wide.

Lay your started binding down, press side up.
Take your Holding Strip and lay on top, Pin into your ironing board cover next to the bias tape.

I like to roll mine to keep it until I'm ready to use it.
I learned this years ago from a Home Eco. teacher in the 70's
No need to buy a machine to do this for you ! But, you can if you like !
