I always used either Faultless or Sizing and would get flakes if I didn't let the Faultless soak into the fabric. I have since switched to Sta-Flo and mixing to the ratio that I need at the time and no flakes if I allow it the time to soak. I recently bought Mary Ellen's Best in the Lavender scent (the only one available) on sale at Hancocks and have tried it in my laundry room with my Rowenta iron to iron clothes and it has left brown (scortched) marks on that iron. I've used the Best Press in my sewing room with my Olioso iron on fabric with no brown marks. My complaints with the BP (other than the browning on the iron) is the smell, the cost, and not heavy enough starching. IMHO, one product doesn't fit everyone's situation. Jinnie
