Here's my fabric...
with your pins, make tiny,vertical pleats
make some more, as many as you would like, depending on the allocated space you want to cover on your fabric or clothing...
tack them together neatly
keep alternating you 'tacks' in a diagonal shape...i.e. down-top-side-side
and you're done!
that's all folks!
