I like that shashing,
I am not sure on the minky, I have done some long arm quliting but have yet to try doing minky, I imagine that it is because it stretches more than anything. though for sure, it is a best guess, so whether they will do it with any on the front is beyond me, I would ask whom ever is doing it, and if it is you, I would do some samples to see how well it works,
