Find the end of the floss and pull out a piece (all 6 strands together) about 15" to 18" long and cut.

Separate the threads a bit at the end so that you see the individual threads. She does this by flicking her finger back and forth right at the end.

Grab one of the strands and pull slowly. Keep a good grip on the other 5 strands, but not too tight.

Repeat for each additional strand needed for your project.

Here she does it "her" way of pulling one strand out so fast that the other strands spin. Note she's got a good grip on the end. If you let go you will have one big tangled mess.

Pulling out single threads prevents the strands from twisting as much while stitching.
I wonder what Katie will teach us next week?
