Pin fabric to paper template and cut out on sandpaper board which stops fabric from shifting, use quarter inch ruler to mark seam allowance and cut out hexagons or whatever pieces you're using with ruler in place, which also adds pressure to fabric - paper template stays in until enough of pattern has been created apart from outer positions - I used to use large glossy calendar-type papers which insurance companies distributed to schools, excellent quality and firm paper, not card stock unless you have no alternative and then find light weight card for some flexibility
