I Can Print This For You
Let me know if you want a printed and bound version of this free downloads. Sometimes it is nice to have a printed version in hand - rather than a digital version to read only at your computer. I can print it on 8.5 x 11" paper, double-sided, using my color laser printer, and bind it with clear plastic covers and a "VeloBind" binder for $20. The finished product looks great.
