This shows the inside of the jeans. I put these patches on in two pieces so that I could butt each patch up against the crotch seam. I'm pretty happy with them. These patches were made from Sew Classics lightweight denim from JAF (leftover from the dog crate) and Heat & Bond Lite. I think that these patches will work better than the ones I did with denim recycled from the legs of jeans that became cutoffs. That denim is a bit thicker - good for a single patch, but not for a double.
And this is the outside - not terribly noticeable! Unless someone is standing WAY too close to her, they shouldn't even notice. I did the V-shaped lines just to keep the two patches together, in case any of the adhesive ever wears out in the wash.
