So now that I've washed this shirt a few times I thought I'd show the wear and tear. The upper lettering with just the Simply Screen paint by Plaid is wearing nicely - no signs of cracking, fading, etc. The star where I first put acrylic paint and then put Simply Screen paint over top isn't doing so well. It is cracking and chipping. I stand by the Simply Screen paint just don't layer it over cheap acrylic paint.
In case you were wondering, these opinions are strictly mine. No compensation of any kind was received for this post.
