Lots of great advice here ... and one other tip:
I find I can move along a lot faster when ALL my fabrics are cut and ready to sew.
So I do everything in stages. Also, I LOVE hockey, so have to set everything aside to either watch my team or attend the game!
Here's an example: (I say days, it could be steps, depending on how much time you have)
Day 1 - figure out what quilt you want to make - that's it you're done
Day 2 - go through stash and pull out what you already have, make a list for what you need
Day 3 - buy all your fabic / threads
Day 4 - wash / iron all your fabrics (OK, I don't pre-wash, but I definitely press them all!)
Day 5 - cut them all up
Day 6 - spend some time studying the pattern and figuring out the BEST / MOST efficient way of sewing the blocks together - I betcha $100 you can chain piece most of it!
Day 7 - chain piece as much as you can without getting confused LOL
Day 8 - press all your pieces, and start sewing again
Day 9 - ??? - keeping doing the above day until they are all sewin into blocks
Does this make sense? I think you are overwhelming yourself so it makes it not as fun ... and there's nothing worse than having your new hobby become a nightmare.
And you are going to make mistakes, and you're going to toss out a quilt top or two (or three or four) - or give them to the cats / dogs LOL ... we all do it ...
Good luck
