One of my quilty friends on our retreat just showed us a problem she had with the Winter Magic type of Mary Ellen's Best Press. This may have been a one-off (maybe one bad bottle) but still--be careful! I've used other types of Best Press for years and have never seen this happen with other types--we suspect it's the green coloring in this one. (Yes--she's contacting the company.)
It sprayed on fine, but when she pressed it, the heat from the iron made the Best Press darken and stain the fabric.
I apologize that this blog post doesn't look pretty but the Internet and cell coverage at our retreat center is sketchy at best so my iPad is struggling to do even this much!
