I have about 2.5 metres of 16oz tartan I'd like to make a scarf of.

It's double width cloth at around 140cm/55".

The finished scarf should have fringed sides and purled ends. To save tartan real estate I thought about ripping the cloth weftwise and sewing two pieces together to get to around 180cm length before purling.

Does anybody have experience with this? Will this fray more because it's not the warp that runs the length of the scarf but the weft?
