I admit I was amazed at how easy my needle went through the aluminum. I did use a very small needle as the puncture marks don't disappear. You want to make sure you know what you are planning to quilt before starting. Although just having needle holes through a piece would make a great addition too.
The sink scrubber was a fun addition as this stuff is just impossible to pull apart. The pieces held their shape and stayed straight up after stitched down.
