Maybe it was the Hoop Ghost that took it. I hope you find them.

I am going to make a hoop bag like that seen in projects, well maybe not as complicated! I am missing a 4 x 4 myself. Live Laugh Download Stitch!

Good luck finding it.

My 1 hoop was also missing awhile back, thank goodness I have more than 1 of the same size. My domestic put it into a box with odd fabric that was on my desk. I found it the next day. I do have place on my clipboard where they all hang. hahah
( look back into everything that you have used) it must be there somewhere. Hugs Yvonne

Hope you wil find it soon. I have one of those hooks that you can put on the back of the door (hasp?) and this is on my rack next to my machines. Those hoops that are not in use I do just hang there (don't have so many hoops) and also these plastic-patterns from Janome to justify a design in the frame; that's my favorite item to loose ;o).

Oh you do need a hoop holder - if you would put your hoops in it - that is.

Been there too. Last year I had an order for 100 Santa hsts with names on them for a local McDonalds. They were given to each employee with a card and money for Christmas. Many names were small so I could use my pocket hoop. the top came up missing so I bought a new one. Got a call from the man ordering the hats and my hoop part was in one of the hats. Now I have 2 pocket hoops. LOL Hope you find yours.

That's one thing I can't stand is to misplace something. Drives me nuts. But I keep telling myself "you know it doesn't grow legs and walk out the door" so it's there some place. When you least expect it, you'll find it. Good luck.
