knitting fuck up

ugh so i have spent days working on a new pattern. Charted, charted, charted some more, made swatches even did some math (yucky). i was finally happy with everything so i settled in to start knitting. 10 inches in, i realised that while everything was working, the design looked right, (my intarsia was a bit loose, but nothing that couldnt be fixed) i realised that i had charted the runes in mirror image. arhhhhh! so i give up! screw the intarsia, i'll just knit it all up and then work the runes in duplicate stitch. i'll leave the intarsia till i am a bit more competent.
