Apple Crumble - without scales!

[lace&pearls]

Hiya, I want to make apple crumble but my only set of scales are broken, I have cooking apples, flour, butter & brown sugar... is it something like 1/2 the weight of flour = how much sugar you need? I can't remember, does anyone know the recipe in cups?! thanks!! xx
