Joining Rows and Dealing With Bulky Seams
Okay. Your blocks are squared up, your top is laid out, and you've probably stood back and looked at it on the design wall or the living room floor at least four times just to make sure you like it. Good. Now we sew the rows together, and this is where the seams start fighting back a little.
Sewing the rows
Join your blocks into rows first, same as you've been chain piecing, quarter inch seam, pressed as you go. Once each row is done, you're joining row to row, and now you've got seam allowances crossing seam allowances. That's where the bulk shows up.
Pin at every intersection. I know pinning feels slow when you've gotten used to the rhythm of chain piecing, but this isn't the place to skip it. You want those seams to nest into each other, not fight for the same space. If you pressed your seams in alternating directions like I talked about a couple lessons back, this is where that pays off. One row's seam allowance goes left, the next goes right, and they tuck together instead of stacking up in one lump.
Sew slowly through those intersections. This is a good place to hand-crank the wheel toward you for the last stitch or two before you hit the thick spot, then let the machine take over once you're through it.
When the seam is just too thick
Sometimes you'll get a spot where four or five seam allowances stack up in one place, especially where block corners meet. Your machine will feel it. The needle will start to bounce a little, or you'll hear a change in the sound.
I broke three needles in one evening once trying to force a machine through a spot like that. I kept thinking if I just pushed a little harder it would go through. It doesn't work that way. What works is slowing down and, if it's really thick, walking the needle over by hand, one turn of the wheel at a time, until you're clear of the bulk. It costs you maybe ten seconds. Three broken needles cost me a lot more than that, plus the time hunting one out of the bobbin case.
If a seam allowance is genuinely too bulky, you can trim it down after pressing, cut it at an angle right at the intersection so it beds down flatter. I don't do this on every quilt, only the spots that are clearly a problem. Don't go trimming every seam preemptively, you'll weaken your piecing for no reason.
Pressing the joined rows
Press the whole row seam in one direction, same alternating logic as before. Use steam if your iron does that well, but don't drown the fabric. Up here with our dry air, fabric can actually take steam better than you'd think without staying damp long, so don't be shy about it, just don't overdo it either.
Check the front of your work after each row goes in. Little puckers hide easily and you want to catch them now, not after the whole top is together.
An honest thing about slowing down
People want speed once they've got some blocks under their belt. I get it, chain piecing feels good, there's a rhythm to it. But joining rows with bulky seams isn't the place to chase that rhythm. It's the place to slow all the way down.
My first attempt at stippling, years ago now, looked like a seismograph reading. Jagged, panicked, nothing like the smooth lines I was trying for. I still have a photo of it saved on my phone right next to a decent one I did later, and I show people the bad one on purpose. Not because row-joining and stippling are the same skill, they're not, but because the instinct is the same. You rush the part that scares you a little, and it shows. Slow down at the scary part. That's true whether it's a stitching motion or a stack of seams under your needle.
Finished beats perfect, I say that a lot in this class, but finished with a little patience at the hard spots beats finished with three broken needles and a bent presser foot. Ask me how I know.
Before next time
Get your rows joined and pressed, and don't be afraid to hand-crank through the thick spots instead of muscling the machine. Bring your top to next class even if it's got a wobble in it somewhere, we'll look at it together.
