If you are going to go beyond making the pattern to making toiles and garments, an iron and ironing board are essential, but there is also other ironing equipment that can make your life easier.
A tailor's ham is useful for ironing curved surfaces, a point presser helps press open hard to reach seams, a clapper flattens bulky facings and edges, etc., and a sleeve board is, of course, useful for ironing sleeves.
