I've seen the idea of tape tracks all over Pinterest (Hands On : As We Grow and Modern Parents Messy Kids have some cool versions) so when I found a roll of black insulating tape in David's toolbox I knew what I wanted it for (not securing wires or some handy kinda thing like that!)
After I stuck down our tracks I used a Tippex pen to drow on lines and details... here's the starting grid and (sort of) chequered flag...
Fillmore's Pit-Stop - by sure to check out his organic biofuel
I am told that racetracks need smooth curves and probably don't have roundabouts in the middle of them... I say pretend play has little time for realism right?
p.s. please excuse my somewhat grimy and awfully patterned kitchen floor!
