Alright. Here we go...sorry for the delay kids! Now let's get down to brass tacks. I know most people use the brown bag method for the Double Wedding Ring pattern, which is completely fine. For those of you not familiar with this term, the "brown bag method" is when you put all your squares in an opaque bag (like a brown paper sack), shake them up, and randomly pull them out one at a time as you piece.
You can piece your quilt however you like, but personally, I don't use the brown bag method. Knowing my rotten luck, I'd get to the last arc and have 6 squares of the exact same print. Instead, what I did was divide my 13 prints into two groups of 6. Umm, Kaelin...I hate to tell you this, but 13 doesn't divide evenly into two. And you're exactly right! For the 13th print that ended up the odd-man out, I divided it's squares between the two fabric groups (19 squares went to the first group, 18 squares to the other).
There are 80 arcs total, so you'll make 40 arcs from each of your two fabric groups. And since each arc is made up of 6 pieces, I alternate that 13th print into every other arc within each group. In other words, for every 2nd arc I make from each group, I swap out one of the 6 main prints with a square of the odd-man 13th print. Aside from that, the rest of the piecing is random - I don't arrange the fabric in the same order for every arc. (I'll show you a photo of what I'm talking about at the end of the post).
Yes, this method is a little more complicated than pulling fabrics out of a bag, but I found the colors and prints were a lot more evenly distributed than when I left it up to chance. There were no light or dark clumps of color, or multiples of the same print within an arc.
So enough with the confusing math, and more about paper piecing.
Grab one of the paper arcs you cut out, and two fabric squares.
Note: If you're trying to arrange your prints in any particular order, keep in mind that we're actually piecing the arc backwards. So whatever prints you sew first, will actually wind up at the end (right side) of the arc.
Flip one of the squares over, and line them up right-sides together (my squares aren't lined up in the picture below because I wanted to show you the direction each print was facing).
Place your paper arc on top of the squares and center it. (I'll show you below what happens if you don't center it.) The first line will be a little over 1/4" away from the edge of the fabric.
Align your needle directly over the first line, and sew on top of it all the way to the end of the paper. Don't worry about trimming away your stray threads, because they'll all get clipped off at a later time.
WHAT NOT TO DO
If you align your paper over the fabric haphazardly (as seen below) instead of centering it...
...when you flip the arc over and fold back your second fabric square, it will be too short and you won't have enough seam allowance to properly sew your 2nd and 3rd squares together. Boo! Hiss! No one wants that, so don't get sloppy or you'll have to break out the seam ripper!
Fold the paper back and trim the seam allowance down to 1/4". You can measure & mark it if you want, but I just eyeball it.
After you've trimmed down your seam, flip the arc over and fold back the top piece of fabric. Finger press or use a small seam presser to set your fabric in place. (It's really not necessary to use a regular iron on every single seam...finger pressing works fine if you don't have a seam presser/mini iron)
Grab your 3rd piece of fabric, and lay it right side down on top of the 2nd piece, lining up the edges.
Flip the arc over, line it up under your needle, and sew down the second line.
Trim your seam, flip the arc over again...
...and press the 3rd piece down.
Repeat this process until you've attached all 6 pieces to the paper arc template.
Flip the arc over so that you can see the paper template. Using a fine, sharp pair of scissors, cut away the excess fabric.
Remember earlier when I said not to worry about those stray threads? If you quickly brush them away from the center of the arc before you start cutting, they'll be snipped off as you trim away the excess fabric!
Voila! Once you finish trimming the fabric to the same size as the paper arc template, you'll have completed your first arc! Repeat 79 more times, and you'll be right as rain, lol! ;)
LEAVE THE PAPER ATTACHED TO THE ARCS FOR NOW. You'll be up crap creek without a paddle if you tear the paper off, because you'll need the paper as a guide (for seam allowances) when you're assembling the blocks.
Oh, and one more thing. Remember when I was talking about all those fabric groups and alternating prints and hullaballoo earlier? Well here's a picture for those of you that are visual learners like me. I made two arcs from each fabric group, and if you look for the white stars, you'll see that I'm alternating in that lonely 13th print. On every other arc I make within each group, I'm taking out one of my 6 main prints and swapping in that outlier print. So when I'm done, 19 arcs in Group 1 and 18 arcs in Group 2 will contain that odd print.
Like I said, the brown paper bag method is simpler, but it's a matter of preference for me. My method takes a little more time and concentration, but it's a good trade-off for me because I'd rather have a bit more control over the fabric arrangement. I really liked how evenly the colors and prints were distributed in my last DWR :)
Happy Piecing! Feel free to post questions in the Comments or email me! I'll try to answer your questions as time allows :)
