My friend is also making the Professional Tote. She directed me to Nicole Mallalieu Design to view the Simple Purse Feet Tutorial. It's worth viewing if you decide to put feet on a purse or tote. In fact, Nicole has excellent information on her site for purse making. Check out her blog as well.
Check out these tutorials for bag making on the sewing tutorials blog. You'll also find lots of stuff for the sewer.
Find free patterns for bags & purses on a previous blog post of mine.
