Men are hard, I have three sons and a DH! My DH first quilt is a variation of an irish chain with wolf fabric and homespuns. I'm making him a man quilt right now. I found a shop online that carries all kinds of novelty prints so his quilt is actually a pattern used for orientals. His quilt has food fabrics (pizza, hot dogs...etc.) energy drink fabrics (that's army guys fuel, trust me they keep those companies in business) then I found a horror movie fabric, casino fabric, cigar fabric. Every fabric that screamed that's my DH.
My sons quilts vary, one I'm making an irish chain with dragon fabric as the middle and the chain is red, grey and black. Another one is getting a blue, grey and black done from a pattern at keepsake quilting called monkey bars. The other one get one made from his dads old uniforms and Army fabrics.
I find fabric I love for them and then do a pattern that showcases the fabric.
