Last year it was reported that Timtex (the heavy duty interfacing) was not being made anymore. So, the great minds at Amy Butler wrote an update for most of their bags using Peltex and Shape-Flex. Both are available at Joanns. They use the non-fusible Peltex and the fusible Shape Flex in conjunction to approximate the feel of Timtex. And, all interfacing will be 50% off at Joann’s over Valentine’s Day weekend. So, stock up my peeps.
In the stash I have a fusible Peltex and a fairly stiff non-woven interfacing from West Coast PR Weekend in Los Angeles last spring. I’m going to use these two instead. Why? Because I already have them on hand 
The update also has you trim the seam allowance on the Peltex by 1/2 inch prior to construction (above). Previously, you would trim it away from the seam allowance after sewing. So, when I made my frankenterfacing, I trimmed the Peltex, fused it to the no-name stiff interfacing (below) and will attach these panels to the fabric.

You can see how stiff it is in the photos above and below.
I’ve worked a little on this bag every night this week cutting out the main fabric, lining, piping, interfacing and fusing. But, I’m about done for now. I need more Peltex for the false bottom and the smaller width piping. This weekend I go back to my sad little blazer. 
I’ve neglected it and let it reside on a spare corner of my ironing board. I need to do a wee bit more sewing on the lining, press a hem into place and make a decision on the pockets. Gah. By the time it’s done it’ll be too warm for a winter weight men’s wool blazer!
