I've seen Edna de la Cruz use a cell board when she's doing her tappits tutorial and it seems that the letters just peel off the board easily. Is this what everyone uses? Is there a better cell board out there one over another? Does it really help when tapping out letters and then picking them up afterwards? I know I have a hard time picking them up from my granite bar which is covered in cornstarch or confectionary sugar. Thanks.
