I imagine corduroy would be difficult to get the wales even. You are brave. I used the dot to dot approach once and found it tedious to make the gathers. I loved to use gingham for making a smocked bodice for my then little girls dresses. Gingham fabric is so easy to pleat and looks very summery. Baby bonnets are also so cute with a little bit of smocking. Alas my girls are grown now with kids of their own and kids today seem to just live in t-shirts and jeans, no more fussy dresses.
