Hi Loralye..looks like Pic #1 is the Tricot Knot iron-on for stabilizing knits...looks like the bottom is the No Show Mesh (not iron-on) but great for quilts and also T-Shirts or any other type of cut-away where you want a soft feel and no-show through fabrics...I have both and use them often..I also take the label and cut it and slip it into the tube so I have it handy when I can't remember what it is supposed to be...which is often for me!

Glad you got your answer. I too learned to stick the label inside the tube. Sometimes the labels can fall out of the tube, so I tape them to a bigger piece of paper so that they fill the tube better and stay inside the tube.

I, like you, got tired of trying to figure out what stabilizer was what kind. I embroidered labels with type and weight like medium tear away and attached elastics to put them on the appropriate rolls. The only change I would make is too replace the elastic with velcro so it fits any size roll. I hope this makes sense. PM me if you need a better description of what I did.
