The pine nut ones I've never made as straws but I do chop the pine nuts anyway. When they are done, I usually put one whole pinenut on the top while they are cooling so it will imbed itself into the cracker/biscuit/cookie round.

The cookie press I use is from Williams Sonoma and it's pretty forgiving if you use the largest nozzle. I've made the Pesto-Walnut Shortbreads as Straws but there again, I chop the waln uts or use pre-chopped walnuts.
