craftgrrl | wonder under problems same thing AGAIN!

new batch of wonder under new crop of material, and iron I know how to run, same problems. it's just not adhereing to the materials. I don't know what I am doing wrong and by this point I could just scream. It's stupid what could be harder than wonder under yet every sample I do works but when I say ok I know what to do now, the actuall product won't work. I am completely floored. Maybe I need to switch brands, maybe go to seam a bond or something, cause I am fed up with this product.I am about ready to trash the notion of making iron on patches. There's no steam I am using dry iron setting the material has been ironed and cooled BEFORE putting it to the wonder under, and yes I am trying to fuse it correctly rough side to roung side of material, no the irons not to hot. No I am not ironing the ptches to long and there for killing the glue. it's just not working when I lay all the pieces out and cover them up an then iron.
