i have a similar experiencing applying grout when setting tile (leaving normal sense...but like a demoniac), tile is frenetic and fast...as it is a large space and most people think a week is a long time. (fxxxdprofession)...but to stop and draw and get lost without pain...that would be something else...that is the material I work with the most, tile. I'll try thinking of it that way when I draw at home and adjust my expectation of how long to take...it would be nice to get lost in some paper. awesome.
