Shivaya

I've been folding my fabric using a ruler and it works great for pieces that are closer to a yard. I have a group that is 1/4 yd and 1/3 yd and ice tried folding them various ways and they either seem to be too bulky or come out differently. I'm curious how others who ruler fold their fabric deal with the small sizes like a 1/4 yd and fat quarters.

Thanks for your help.
