It thin it’s really nice and actually was able to learn a few more trick of the trade always a good learning experience in the morning a good way to sit with a coffee and feeling your sense of humours as well you are an excellent teacher you are one of the biggest influence for me to start leatherwork thank you from the bottom of my heart. c.noel canada
