Hi Sum, I was wondering if you have been annealing the aluminum panels before they are formed? Are you free forming some of the bigger panels? On the top piece, did you use a "hammerform pattern" or free form? Would it be possible for you to capture "sum" of your techniques with the camera? Hey, I know you are busier than a 1 armed paper hanger with all the projects going on so if this these questions require to much time to answer, I DO Understand. Take Care, Mike R.
