sry to revive this thread but i have a similar problem
and i cant really imagine the things you explained

or maybe i got it wrong..
anyway.. to clear things up i thought pics say more than words..

this is what my design looks like..
I had 2 different kind of cloth (100% polyamid & 100% cotton)
cut out a traingle from both and stitched them together..
first i tried sewing a chain in (red line) but it was very heavy and uncomfortable.. but at least the flag didnt wrap up while playing..
now i got rid of the chain and have only two links left which connect to the swivel/handle and instead.. i put some weight in the corner only.. it worked a bit better but still.. wasnt quite right.. and now the flag keeps wrapping up..
i managed to search the forums and also couldnt find the infamous dom flag design.. but anyway those weighted curtain cords are what i needed i think..
but now i dont know how to put them in there..
should i put them in there like i did with the chain?
should i weight the corner too?
im sure the flags wont wrap up this way..
or could it be a good idea to make a more curvy disitribution of thw weight.. (green lines!) a long one on the ledges and a smaller one inside..
but i dont know how long i should make them?
anyway like this.. the flag will wrap up again wont it? though i got the swivel..
