I watched a segment on Martha's Sewing Room with a Rep from Schmetz I think. He was saying our needles are the least expensive part of the sewing process! Buying in bulk I think they are much less than .75cents each! When you think about it, that's pretty true. A single spool of thread these days is spendy. Sooo... it makes it easier to justify.changi g needles more often realizing they really don't cost us a fortune!
