I tried the Log Cabin assembly style and it was a disaster. I ended up doing each block individually. Sometimes I may do one step assembly style but then I get bored and need to mix it up.

Try working on a simple pattern and use the assembly method. Using this process on a complex block might be the issue

It's your quilt so you do what works for you. I'm not fussed on chain piecing. I find I start making small mistakes but added up they are A big one. You know what feels best for you. If the quilt police call don't answer the door.

Guess it is good that rhere is no quilt police...lol.

I'd switch back and forth for variety. When I get bored of one, then I go to the other method. If I don't want to think all the time, then I'd lay the pieces out & chain sew them. Then when I want to use the right brain, I'll stop & do 1 block at a time. I also have smaller projects, like the tissue covers, all cut out ready to go for when I want a break, really don't want to think or get tired of looking at the same project.

Yep, been there done that!.... Some I can, some I get to turned around and find myself using "Old Blue" aka my favorite seem ripper.

After the first one or two 'test' blocks I like to somewhat assembly line sew - but in small batches. So I might do six blocks at a time which moves things along but still gives a nice feeling of satisfaction upon completion. It also changes up the activities so I don't get bored/sore doing the same thing for too long. The only exception is cutting the pieces - if there are a lot of different fabrics involved, then after the test blocks, I cut everything out so I can pick and choose which part to work on next without having to layout/square up all the fabrics every time.

I had a hard time at first with it, because it seems so overwhelming.. Maybe try to do 5 at a time the move up to 10, but like others said, there are no rules it is your quilt, go at your own pace.. The idea is to have fun and enjoy what you are doing.

Isn't it wonderful how different we all are?
How boring the world would be if we were all little clones of the same person.
No matter how you go about piecing your blocks, if it makes you happy, it is the correct way.

I mostly chain sew because of the time and thread saved, but sometimes I just can't wait to see a finished block, so I go for it!

assembly line sewing sure does get you done. i always do a couple blocks 1st , to make sure they are the rite size.
