When i sew the corner part of this bag, i got trouble...i think it would be easier if it's 90 degrees sharp or more round . If the corner round is between, not really round and not like 90 degrees sharp, it's more difficult in sewing it...i felt that when i sew the bag...i thought sharp degrees will be more easier, or may be i should make it more round...i looked up in my japanese book reference and i found that mostly are more round...
sharp corner is more easier to sew.
see the corner? the left pattern's is less round than the right one's.
