Is there any thing to do for iron on patches to stick

I find the iron on patches stick better when the corners are rounded and the iron is at the correct temperature.

Add additional washable fabric glue

Once the "glue" on the backing of the iron-on patch has been activated, there isn't anything that can be done to get it to stick again, other than trying to adding new heat activated glue (which may not be fabric friendly) or adding a new backing with iron-on- interfacing (which may not be vinyl friendly). It is also often very difficult to get iron-on patch to stick to old glue residue that may still be present on the fabric.

How is the patch staying put with your hand sewing? I am wondering what style of patch you used, as usually these are made from vinyl and tend to rip once perforated with a hand sewing needle.

If it doesn't meet with your expectations with holding on, then repost your question telling what you have done, with a picture of what you have now.

If you go to your local arts & crafts store and ask for a product that is called "stitch witchery" or it may be called by another name. The sales person should be able to help. Follow the package instructions but I recommend that you use waxed paper as a buffer between the ironing board and the fabric. The waxed paper keeps the fabric from sticking to the ironing surface.

I have tried many things for this exact same problem. Other than stitching it in place, there isn't much that will hold the patch if it is in a place that takes a lot of stress, like elbows and knees. Which is exactly where the fabric wore out that needed a patch in the first place.

I'm having the same problem. my iron on patch on my pants keeps coming loose and even when I use an iron again over it, it does not work
