Heeehheee ...
Another great example of US knowing more about sewing, than the people working in these stores ...
like ... one time, last year = a Jo@nn's STORE MANAGER told me that "there's no such thing as ELASTIC THREAD! I know EVERYTHING WE SELL HERE & there's no such thing!"
I politely said "it's what you do shirring with. You wrap it on a bobbin & sew with it, on your machine. Like the little sundresses we had as little girls." ...
She got huffy & snorted at me "I don't know what THAT is! But I know for a fact, that you can't run elastic through your sewing machine. You HAVE TO sew elastic TO the fabric with thread. Our elastics are all over there." ...... grrrrrr
I finally found it in the notions area, hanging on a peg wall. I POLITELY showed it to her & that the package says "ELASTIC THREAD" (I made sure to be NICE as I did that, though) then I turned it over & showed her the back = INSTRUCTIONS on HOW TO SHIR with elastic thread ...
geez ...
She YELLED at me (as if, she just could NOT possibly be wrong) "well, THAT's a notion, NOT a thread! Since it's in the NOTION SECTION, and NOT in the THREAD SECTION." ...
I just calmly turned around & walked away. argue+brick wall=silly ...
I only showed it to her, IN HOPES that she MIGHT remember it, IF anyone ever asked where it was, in the future. NO sense in someone else getting treated that way, just for asking, ya know?~! I'm pretty sure she won't forget that incident very easily.
FYI = There's another brand/CLEAR in their crochet/knitting/yarn area, too ... heheeee

and they had pre-shirred fabric, too!
