How do you make flags waiving then the wind from a decal?
My preferred technique is to use Heavy Duty aluminum foil, the regular is a shade too thin.
Align a fine bit of thread (6/0 suture thread, 25 dernier silk, whatever) to one endge of the foil. It helps to have something withe really flat clampint surfaces (I used to use wooden spring clothespins with the legs inverted and sanded flush to each other).
Now, stand that assembly, thread side up between two bulldog spring clamps.
Now, you will be able to drape the flag decals over the foil on both sides, with the hoisting thread pinched inside.
Let that dry thoroughly, then use a brand new xacto blade to slide the foil free (leaving the thread intact.
At 1/350 only national ensigns are worth that much effort. For signal flags, just string a thread between two handy objeccts and drape the decals over that thread to adhere to themselves. To scale, each signal flage ought to have 72" of lanyard, which is 0.205" at 1/350, call that 3/16" a hair over 5mm. (From the top of the signal flag.)
