I was a bit concerned with using 0.5mm plastic sheets as the thinness would provide less contact. It is far easier to cut, but more care is needed as it tends to slide and the straight cut gets skewed. The thinness was less of an issue when joining them at an angle and suprisingly still provided enough contact for the glue to stick them together.
