Did you know Brand Name Jeans have their own brand of threads? You won't find the same thread color and hard to search for it.
Therefore, heehee , when hemming Brand Name Jean's I use the ORIGINAL THREAD!!!
HOW? First I carefully extract it. Iron it. Wax it to make it stronger. Iron it again to absorb the wax in the thread. Wind it in the bobbing and STITCH it BACK ON!!!
Result: looks like it wasn't even alter in the first place
