I've always said that I'm one that dislikes having to iron things. Don't get me wrong, I do iron when assembling blocks but when the items get larger, I dislike fighting them on the ironing board. Plus, by the time you iron the bottom, the top part is on the floor and wrinkling again.
So, I've been a fan of steaming my backings. Just enough to get the major wrinkles out. There are always little ripples here and there but it's good enough for me. I don't create quilts for competitions. So, I fold up the backing and hang it from my steamer and a few minutes later, I'm ready to load the backing on the quilt frame. I usually steam the front folded item and the back and reach in and get the inside too. Wrinkled on the left and steamed on the right.
I loaded the Hunter's Star quilt backing yesterday on the quilt frame and had to take photos as well. Every time I pin a quilt backing to the top and bottom leaders, I watch constantly for balance. However, the one thing I always forget to do is to wrap the leader around the tension pole (my name for the pole) In the end, I always need to pull out that pole and replace it on top of the quilt. It makes me laugh that I continue to do it every time. I might as well accept this as my normal. I guess it's because when pinning the top part, it's too hard to pin around that pole.
