bought a 100 yd ball of this stuff fer just under 5.00 from wally world and was thinking of useing it fer my bag....it looks like 1 - 1.5 mm in dia....i tested a length of it off another ball from the shelf that had bout 3' unrolled from it....i stepped on the section just off the roll and wrapped the loose end around my closed knife and pulled hard to try to break it and it stood it's ground....after some waxing i think it would stand up to use as thread fer my bag....the color is a taupe/beige on the label but it's a dark beige....i know it may not be pc but i need it to hold up fer my use as a hunting bag....just posting a source fer thread.............bob
