Threadart Wooly Nylon Thread - 1000m Spools - Color 9101 - White - Serger Sewing Stretchy Thread - 50 Colors Available

Can one avec use this thread in a regular sewing machine?

How many spools of this should I use when making leotards? I've heard just the lower looper, just the upper loopers, and all of them. Any advice?

can I order more than one at a time
