I am using the Facebook group, American Patchwork & Quilting's UFO Challenge, to motivate my work on UFOs.
You fill in your list with the projects you most want to finish (or move to a new stage) during the year. They draw a number each month, and that's the UFO you focus on for that month.
I've filled in two lists - one is quilt tops that I want to get quilted and fully finished this year. The other is quilt projects that I want to finish the piecing on so that they reach the Flimsy stage.
How I work:
Monday thru Friday, I restrict myself to the priority projects - 1 piecing, 1 longarming. This year, those will all come from my UFO lists. Typically I'll piece in the early morning and quilt in the afternoons. After dinner we like to watch 1 or 2 shows, and I'll do hand applique work during that time if I don't have a quilt binding to stitch down.
Saturdays, I let myself work on whatever project calls to me, to give myself a break from the priority work so I don't lose my MoJo.
Sundays, I always work on a BOM, which was often worked on the day before.
Thru all of this, I keep a leader-ender project to the side of my machine, so that one just kinda does a low simmer that one day magically appears as a bonus quilt top.
This approach works extremely well for me.
Number 7 was drawn for January's UFO work.
Longarming List:
1. Marissa's UCCS Graduation Quilt
2. My King'd Dinner Plate Dahlia

3. Rainbow Jane
4. Set Sail
5. Plums in November
6. Thistlepods
* January! 7. Modernology I've finally had enough strength to start longarming again this week - only 1 hour max per day, but I'm happy with that. First I have to finish the quilting on my Sew Spooky, then this beauty will get loaded!
8. Listen With Your Eyes

9. From the Heart
10. Allietare
11. It's a Silky wool Flannel Kind of Day
12. Martha's Christmas Whirl
Piecing List:
1. King sized Garden of Dreams - Panels are partially made

(I'm king-sizing this Kona pattern. Lots of math involved, since I didn't want to simply add large borders all around.)
2. Down the Rabbit Hole - Finished the sunflower round, need to do the rabbits border and the outer diamond border

This one is on my BOM roll, but I wanted to dedicate a month of priority to it as well.
3. Whooo's Your Mama - needs the stitcheries
4. Collections for a Cause: Legacy - At least some of the patches were made.

I think I made the windmills? But maybe just the HSTs. I'll see when I pull out its box.
5. Stepping Stones - blocks are made

This was my first Judy Niemeyer pattern. It quickly got sidetracked by more intricate patterns of hers.
6. Amaya - need to do the collage work
* January! 7. Let's Build a Snowman - applique has been fused for all the rows, needs stitching and piecing
8. Climbing Lanterns - I think it's ready for the 3D pieces to be done up?
9. Chubby Chicks - I think the applique has been fused. Well, main bodies have been, looks like.
10. And to All a Good Night - applique panel is started. Will be king-sizing the pattern.

One of the many Sue Garman patterns on my bucket list.
11. Spanish Tiles - fabrics are boxed together

(The original in the quilt pattern book "Living Large")
12. Fanciful Flight - a kit. fabrics have been washed
I actually printed empty lists on the backside of both of mine, for write-ins of extras as they occur, like my BOMs, leader-enders, or left-overs.
So far, my Water Reflections BOM is written in as an extra Piecing UFO that's been finished, and I'm currently working on the quilting of my Sew Spooky UFO that I'd loaded up before COVID hit me. I don't want to closet it yet again, so it has to get quilted before my #7 gets loaded for the January UFO call. I'm hoping that happens before January is over, but longhauler issues dictate how long I can work at the longarm each day (or even if I have to take a bye day still).

1st Flimsy!

In longarm progress!
So! My 2021 quilting work will be almost completely driven by these goals. Here's to accomplishing a lot of them!
