CD Weaving- the warping

Start by looping the string through the center hole, and tying a snug knot.

Slide the knot to the center hole.

While holding the knot/CD with one hand, start passing the end of the string through the center hole, and pulling tight each time.

An odd number is necessary.  When students had their CD strung, I tied the two ends together in the center, and they clipped the tails. 

Tie the weft, or the weaving string to a center string, consider it "over", and start weaving. 

Voila!

I have had a couple of requests to show/give more detail in how to get the CD warped and ready for weaving.  Understand, I did not think of this idea, I found it on pinterest, so there may be other ways- this is the way I figured out, and it works... mostly.  As in anything, there are always a couple of kiddos who need me to rescue them.  But, the success rate is higher than with the paper plates- and the weavings stay centered, which does not always happen with plates.  The one problem this group had was counting their warp strings and stopping at odd- I think they were losing track of where they started.  My "fix" for the ones I didn't catch was to take 2 strings and tie them together, and have the students consider them one string. Using the CDs is a manageable size, easy to store, and sturdy for the "determined" weavers. Also, lots of embellishing potential.  I used feathers and sequins, but there are a wealth of things you could use to finish off the edges.
