Thanks for all of your input. I originally googled "Pauline's Quilter's World sashers" and came up with a number of sites and different set combinations that are available. There is even another manufacturer that sells what looks to be very similar items, but most of them are from Amazon sellers with unfamiliar names or lower ratings that I am not too sure I'd trust. There is one set by Pauline's that is just for 2-1/2 and 2-1/4" binding strips called the mini set PQW-02 and it is available from Missouri Star, and there is a single for 2-1/2" strips called the jelly roll sasher. Hope this additional information is useful for some of you.
