what you should have done is place a teflon pressing sheet over the piece that is fused down and heat it up with your iron and peel it back off immediately!
however you now you can not easily remove that sticky stuff, nor can you remove the PINK tinge the red left....NEVER use red on white unless you really wash the red first..
another thing..was the white washed?
ALL fusible webbing will tell you to make sure you are using WASHED fabric before applying the fusible..the chemicals on the fabric react when the heat is applied to the fusible webbing...
can you post a pix...
