The Kaufman Mammoth flannels are the best that I’ve ever used, The quality fabric is great to work with. The colors, feel of fabric and durability have lasted for over 3 years, with regular washings.
The only issue I’ve found is that when people see a finished shirt, they ask ‘where I purchased it’. When I tell them that I made it, they have begged for me to make them one! 😂
