sizing gets a bad rap as many manufacturers use it to make the fabric feel better quality than it is...we've all washed fabrics that lost all their 'body' after wash/drying...what they really lost was all their sizing...it has its uses and starch over sizing is really just personal preference... just buy a can of both and try them...the starch will make it much stiffer and may be repeated for more body... the sizing gives body with the shine of starch... some people like one and some like the other... $5 will settle it for you....
