UPDATE_ FOUND LINK_Good evening (here anyway) Cuties! When I went to my QOV meeting a couple ladies had these very large bags they had made. Naturally, me being curious, I had to figure out how to make one. lol And of course I had to have one too, to bring all my 'supplies' back and forth.
One of the ladies told me the pattern came with a certain iron on interfacing with grids marked for your 2 1/2 inch sqs, so you HAD to buy the pattern. (She doesn't know us Cuties, ha ha )
Well, I can mark a grid on interfacing and I googled Mondo Bag to see how to put it together, on You Tube. I also had this pack of charm sqs just waiting for a project, so I cut them into 2 1/2 inch sqs and added a few from yardage so here is my result.
I quilted my lining using my walking foot. I used everything from my stash, even piecing batting for my lining, as I didn't have fusible fleece. The charm pack was a gift from someone who went on the MSQC bus trip.(wasn't that nice?) The lining was fabric that was given some time ago, maybe from my aunt ,when she could no longer quilt. The very bottom ends up being about 11 inches sq so it's humongous! I could probably get my little machine in it! Anyway, I hope you like it and I didn't forget my name! Can you find it?- Well, if you like it and need one, go for it! I know you can do it! Toogie
You are so right about the Internet, kids say 'just google it' and it's true. You can find anything.
I've made some bags using just 12 4" squares. Much simpler than your pieced blocks, but same way to sew them together - and smaller of course. Bernina had a Permission Bag in one of their Through-the-needle-off magazines years ago where every 5" felt block was embroidered - pattern still available at Indygo Junction.
But you are right: Cuties just have to see it and figure it out themselves.
