Very interesting approach Rosemary, I will look forward to the blog too.
Meanwhile, back to the foot pedal.... Well I couldn't find a mouse pad while I was in a nearby town this morning but I did find something that has really worked! A bath mat! They just arrived into Penneys - a memory foam bath mat. Velour on one side and a rubberized back. I put some velcro on the back of the foot pedal (the rougher side of the velcro) so that it sticks to the velour. The rubberized underside of the mat means that it isn't going anywhere. And I have a nice soft cushion for my heel and my other foot to rest on. PROBLEM SOLVED.
