Thanks for the info, I will be machine straight stitching the leather appliques to the fabric, and if they are stiffer, that is good, makes them easier to keep in the shape I want, so they dont flop all over. I just have to experiment on how well the leather would hold up to ironing. I use some metallic leathers, that have kinda like a tinny type of bonded surface, so have to see if that would melt. I just basically need to have it positioned and hold in place, if the fusible stiffens them til I bond it, all the better, as they will not flop as much when I am positioning them.
Another question for all you knowledgeable people. When I position the appliques, I start on one side, lay down the appliques and decide where I want them,then I need to mirror image them and put them on the other side the same, any idea on how to position them the same on the other side? Maybe make a template??? I kinda freelance and dont often use the same pattern very often......
