Does your local laundry know how to properly press your shirt collars?
Do you get complaints about collar bands breaking and falling over?
The attached images, could prove to be helpful for you, to communicate with your local laundry that you recommend, to better service your mutual customers.
The main issue is when the laundry “cracks” the collars, the technician pulls the collar over a heated cone, if they pull down too tight on the collar leaf, they will create a break in the lining of the band. By slowing down and properly creasing the collar leaf, this issue can be generally avoided.
I hope you find this to be helpful
