I have used all of the methods listed but my last scrappy quilt I used this and was pleased with result:D

This is the approach I'm leaning toward; I have tried a variety of systems and some have worked quite well, but I want this one to go more quickly so I think I will throw caution to the wind and take my chances. I will post the end result :)

Since it is only 3 colors, I would not call it scrappy. Make a pattern on paper, have your tumblers next to you and Began to sew. No matter what you do your son will like it.

Oh man...too bad you're not more local, I would love to intervene! LOL I love scrappy quilts, crazy quilts...bring 'em on.

Just do one. You can do it. Just ONE quilt. Cut yourself a bunch of squares from fabric that you like, toss 'em in the dryer or shake them up in a bag to get 'em all nice and mixed up and just sew them together into rows, without looking! Then just sew your rows together as you finish them, no editing. YOU CAN DO IT! Just ONE quilt, and if you don't like it you can donate it to charity and you don't ever have to do it again because you'll know for sure it's not for you. (And then you can send all your scraps to ME!)

But I bet you'll like it. ;)

Take the time to lay it out on the floor, photograph it, then pile all rows up with the top piece being the right side of the quilt and numbered accordingly. Then take all piles to machine, and verify with photo as you sew. (My design wall has fur-kid feet that want to 'help', so I can't leave it out to look at.)

id put all the reds in a bag.. All the white in a bag#2... and all the blues in a bag#3..

then sew rows of colors.. row of red.. a row pf white.. a row of blue...

my sewing machine sits on a wheeled cart. when I am ready to sew the top together, I lay the blocks out on the bed. I decide what goes where & also if I need to make it wider or longer or want to add sashing. I guess you could say that is my design wall. LOL last step is sewing it together! NO problem!

It depends on the shapes of your pattern. Could you gather like in hexagons, do them like rosettes then you add them together forming bigger shape and so on. And if me I will bring the machine to the same room . Finally I will fix to a bed sheet with pins or scotch-tape

Sewnome is right , make it easy as it is scrappy pic them randomly and you will like it sure course it's your art

I made a design wall out of some flannel, a thin curtain rod, and a row of grommets across one end. I put that up in my sewing room and it has literally gotten me up off the floor. I made it 60" wide by 60" long, and I love it!
