don't you stop to ask him why... he'll just look at her and cry..
til she gives in and sews it oooon and he'll tell her "Mooooooom, you
know I love you!! " ( apologies to CSN&Y)
(personal experience) The aerosol can works , but not permanent. On the BACK of the patch, shoot a small bead around the edge of the patch, just inside the edge. With putty knife, smear it around til you have a thin even coating. On a table, QUICKLY place the patch BACK DOWN in place on the uniform, and place wax paper over it. Stack some heavy books on top and leave it over night.Next morning, carefully peel off the wax paper. Artfully done, no smear out the edges of the patch. It will eventually fall off, depending on how strong your laundry detergent (lasts longer if you never wash it!) Will NOT stick to nylon jackets. Plastic backing allows patch to be peeled off cloth. Soak Back of cloth with wd40 to remove most of stickum, but some stain will remain, no matter what.
The sheet material is more permanent. I used it for my new uniforms when I had to get ready for Jamboree. Follow the package directions AND::: place a white handkerchief over the patch and iron (wool setting 30 secs.)Avoid getting it on the iron at all costs. DO NOT DRY CLEAN. everything desolves and patches come off. You can touch it up with another litte piece of stickum, should the patch start to peel off.
I would never use either for the wool leader jacket, but the patches on the Cub Scout poly felt vest have not come off (aerosol can stuff.)
