I would really like to try this but I have a few questions.

I have never used elastic thread, is there a special technique to winding the bobbin?

I am also a bit confused as to what you mean my this tip:
"TIP: keep track of your elastic thread and if you need to switch the bobbin you will want to finish the row at the end of the fabric as opposed to the middle"

Thanks for taking the time to write up this tutorial, the pictures are great, you make it look so simple. I hope it really is!
