Tell us about yourself!
Technically, you could do either. I placed mine on the outside. They do weather over time, but mine has held up fairly well. I figured it would be pretty easy to remove/replace if it ever deteriorated. If you place it on the inside, it will probably last a bit longer. You would, of course, need to consider the direction of text. If you have text on your decal or need a specific orientation, you will want to mirror the image so it prints reversed. Then when you apply it to the inside of the window, it will still look correct from the outside.

Nice! That looks really good. Mine has worn as well and has some looser wraps below the tacks as well, but it has really held up very nicely. I've thought about re-wrapping it, but haven't had to do it yet!

The only suggestion I have would be to try to avoid excessively detailed elements in your design. The details I lost were because I had used a very intricate font with very tiny trace lines. That left very small areas of ink that will be more likely to wear or wash away. Other than that, make sure you get decent ink coverage and sufficiently heat set the ink to avoid degradation. This has been a while now and the designs printed in this instructable have held up just as well as any commercially printed shirts that I own.
I haven't checked for it at stores like that, but it's possible. You might have better luck at a local fabric or craft store, but I'm not positive. I've only purchased from online sellers. If you find a good alternative local source, please share what you find here, so it might help others as well!
