You name it, I've done it. Biggest complaint - not enough fabric and buy the time you discover that you don't have enough fabric, either the store is out of it or the dye lot has changed.

I am so glad you didn't ask "how many" mistakes I have made. LOL

I think my BIGGEST mistake was a few years ago at retreat. Decided to do a Minnesota Hot Dish pattern (easy), had all my fabric cut and even made a sample block. All set to do the 80 blocks. Sewing away, doing 40 blocks, chain piecing at a time. Was about the third round, ready for the fourth round. oh, %$*&)**($ All 40 of the third round is on the wrong side and will make a differences of the layout of the quilt ..... spend a lot of time unsewing...

I think the one I regretted the most was rushing the laundering of a very large wedding Queen quilt for my daughter. I washed it once and then tossed it in the dryer. All the quilting lines had not washed out yet so I set them in the dryer. She is fine with it and loves th quilt. I hope that over time they will dissapear.

LOL - been there!

I made a Lone Star but apparently I had turned the bits the wrong way so my star radiates into the point (which is kind of cool) but I really mucked up the angles. Working with all those bias pieces was not a good idea for a total beginner. One of these days I will pull it out and fix it.

The first quilt I finished. I generally make one block at a time now, but I'd just kept putting blocks together & then I realized I had been having so much fun putting them together, I had enough for two quilts and a pillow! LOL!! I kept one & the other set made a great Christmas gift!! :-)

Sewing a block together and realizing I'd sewed it wrong; ripping it out and sewing it wrong again. Now I know from firsthand knowledge "third times charm".

Two weeks ago, at an X block class, I sewed a bunch of strips together in the wrong order. Wide, wide, narrow instead of wide, narrow, wide. How could I have been so stupid? The teacher, bless her dear heart, just laughed and grabbed some of them, unsewing as she walked around helping people. Later, I sewed some blocks together in wrong order, too. But it's done now, and I love it. Not necessarily the worst mistake, but the most recent, and I remember it. LOL

I had a quilt that I was going to put a border on and the fabric was directional. Do you see where this is going? LOL I have learned not to cut fabric after 9pm. This mistake required a trip to LQS. :-)

Toooo funny, LOL.
