craftgrrl | stitching glassine envelopes (hints needed)

Hey craftsters!

I would like to make some "envelopes" out of glassine (which is like glorified wax paper) by stitching with a sewing machine up 3 sides of the traditional envelopey rectangle.

Our sewing machine is older than me - so its real basic and its nothing new fangled or from any era ending in 80's or 90's.

I was thinking of using just normal thread. Pink be the color!

Got any tips or hints for stitching on paper? I am crossing my fingers that you do!

Thanks in advance!
