Im talking 10 20 yards, not 2 yard. Ive only been in business 4 years and I gave up measuring the beds out 2 years ago. Im sure you guys will look down upon me for doing this but I often feel that perfect calculations take too long and if Im + or a yard its ok. I usually overestimate it so I dont beat myself out of money but Ive been short a few times. Sometimes Ill charge the customer for it, sometimes I will but the 18 bucks and time I loose if Im short. Do you always measure it.
