every year an elementary school in california runs a festival where families sign up for parties and events, as well as bid for auctions and donations. each family is issued some stickers with unique barcode to make it easier to sign up.
i couldn't figure out how to get avery on-line mailmerge to do all i wanted (scale fonts to fit, skip missing parent's names, repeat labels etc) so here we are.
pip install reportlab
pip install openpyxl
pip install pylabels
code is written to be thrown away after it's first successful run :-)
