I was happily working along making my daughter a messenger bag. Until I got to the gussets, which left me confused. The pattern sheet says to cut two out of fabric A, so I did. But when it came time to attaching them to the side panel, it seems that instead of two identical pieces that they really ought to be mirror images of each other. After searching out errata information on the bag, I see nothing about it posted. But I am seeing lots of successful projects on flickr! Is there an error in the pattern? Did everyone just realize it and cut out what they needed? Or am I confused as to how to orient my identical pieces. Thanks for the help!
