Anyway... with that self-recriminiation out of the way .. Let's think about the handles for our purse/bag. We will be using 4" wide strips for the handles. I have cut 3 - 4" x width of fabric strips for my handles. I also have joined them end-to-end on the diagaonal so that I have one long (about 120 inches) 4" wide strip.
To join them end to end, start by laying two ends face to face as shown here and marking from one corner to the other corner, this will be a 45 degree angle on your ruler.
You then want to sew on this line and cut off the triangle.
I press my diagonal seams open to reduce the bulk.
Next, we need to press this strip in half lengthwise.
Re-open the strip and press each raw edge to the center crease.
After both edges have been pressed to the center, you want to repress your first crease.
At this point, if you want a padded handle, or one with a bit more "umpgh" to it, then you can add a 3/4" strip of batting inside these folds, or even use some interfacing.
Before stitching to secure the folds, test the length of the handle against your purse.
Lay out your handle so that it looks like this:
Now you can join the two ends of the handle on the diagonal, but be very careful not to twist.
Next, you want to sew 1/8" to 1/4" from each edge of the handles, plus perhaps a decorative stitch down the middle.
The next steps will envolve adding the handle to the purse base :)
Exciting isn't it?
