Im sure you will enjoy the class when you are able to take it.
I have been making these since before there was patterns and classes. I developed my own process. I dont use any fusible web. I construct it similar to the quilt as you go technique, so, when I put the last row on, Im done. No more quilting, just add the binding.
The t-shirts hold up well to use and laundering without any stablizer.
However, if you are going to make it like a traditional quilt and then have it quilted, you will need the stablizer.
Let me know if you want directions to my process....
