What not to do with Wonder Under

I've been working on baby bibs lately. I'm using recycled denim and bandannas, and going nuts. They're so much fun and stitch up in a few hours from start to finish. Last night, I was trying something new. I made prairie points to go on the edge of the bib. Made these out of a green bandanna. My master plan included cactus appliqué cut out of the same bandanna, as well as a cowboy hat and a star. Cute, huh? Well, yeah. Until my blunders!
First I pressed the Wonder Under on the RIGHT SIDE of the appliqué fabric. Uh, no. It goes on the wrong side dernit!
Second, I pressed the WRONG SIDE of the Wonder Under. Lawdamercy, was that a mess! My iron was not covered, but certain spots were because I didn't catch my mistake until the deed was done. If you ever do this, you'll see that you can't use your iron until every smidgen of that glue is off the iron, or it won't move on the fabric.
Now what? Toss the small piece that I pressed on the right side of the fabric. That's simple enough.
But that iron. Oh that iron. I put it on the highest heat and pressed some muslin scraps to try to get the WU glue off of the iron. Nope. I turned it off and let it cool and tried a plastic type dish scrubbie thing. Nope. I looked for steel wool, but nowhere in my house was there any. Last resort, I found an SOS pad. It was dry, so that wouldn't be quite as messy if it was wet, right? Well, after 10 good minutes of scrubbing with a dry SOS pad, the glue came off, but I had blue soapy stuff all over the ironing board, the iron, and myself. Took a while to get it all cleaned, but I did it.
Lesson to be learned - Check the placement of your Wonder Under on the fabric and to make sure you use it glue side down. It's an amazing product that I use frequently for appliqué, especially on something that will be used and washed more than once or twice.
The good news is that I finally did get the three appliqués on the denim and basted the prairie points to the outside edge of the bib. When I'm done with my Jamestown 400th sewing over the next few days, I'll finish the bib and put pictures on FrugalSewing.com, but golly, this thing is taking forever!
