actually we did do that in jr high sewing class but that was back in the 1950's when the boards were all strong enamealed steel.....actually still have mine (was mothers but she bought an "not soooo heavy" one when i was in high school and I adopted this one....saved it actually from the trash, she was putting it outside just as i came home from school ) which i use almost every day and the narrow end is very solid not wobbly like the ones in the store now.
sorry did not mean to be so longwinded
