I am a person of habit. I just don't like change. But sometimes I just have to try something new - many times it's because I've heard about a new product that promises good things. But to be perfectly honest, most times it's a money thing. I've always been a fan of Heat n Bond, and I do a lot of applique, so I use a lot of Heat n Bond Lite. But the last time I was running low of fusible, I received an offer on Wonder Under that I just couldn't refuse. So I ordered a couple of yards. It seemed flimsier, but it was all I had. So, I traced my pieces and fused them to the fabric. So far so good! I did find that it was, at times,a little more difficult to peel the backing off. But. I took my time, and got the backing off clean. This morning, I fused my applique pieces to the background blocks. I have to tell you, I am so pleased with the results. The Wonder Under is not nearly so stiff as the Heat n Bond. And, it seems to be sticking better to the background. No one is paying for me to say this, but I truly believe that I will use the Wonder Under when possible. Don't get me wrong, I'm not dissing the Heat n Bond, I just prefer the feel of the Wonder Under. And, I think that I will have a more open mind when it comes to trying something new.
