|I made my daughter a Simplicity nightgown pattern that called for you to iron the wide bias tape used flat. The garment took quite a bit of bias tape, and ironing all that tape flat was less that thrilling. I remember even burning myself doing it.
Yesterday I made the gown again. This time an idea hit me. I went into the bathroom, grabbed my flatiron and used that to iron the bias tape. Easy and simple. Open the tape up and place in the flat iron, use your other hand to pull it through. Once I got a rhytmn of sorts going, the folded parts opened themselves up as they slid into the flat iron.
This was much quicker to me than opening up all the tape and ironing it on an ironing board. Maybe it will work for you too!
I don't know if this would work with a cheap $20 flatiron, as I have a professional model, but it's worth a try!
