I think that makes sense. If I don’t trim the long piece, should I align the edge with the longer piece (so there’s a gap between the shorter piece and its corresponding edge) or align it with the shorter piece (so the longer piece overlaps its corresponding edge)?

a question about joining tube pieces together (step 2). What is the tolerance for the corners lining up of two pieces that have been joined together? In spite of my best efforts i still have about a 1 cm difference between the two. Do I have to redo the seam?
