If you’re looking for a real thread color chart and not one of the wildly inaccurate online ones for Maxi-Lock serger thread, someone on Facebook is selling them for $35. We are in the same state but since she’s not super close to me I asked if she would be willing to ship it to me. She charged very reasonable shipping and it arrived quickly. The swatch cards are sturdy and there’s a nice big ring to keep it all together. Her communication was excellent as well.
Here’s the listing if you’re interested: https://m.facebook.com/story.php?story_fbid=3071557416334323&id=886555474834539
