Things You Need Before You Start a Knitted Top
I keep a running list for every top I knit. It started because I kept forgetting things mid-project and either had to order yarn late at ridiculous shipping costs or ended up with a garment that didn't fit because I guessed wrong on gauge. The list has evolved over about twelve years and thirty-something tops. Here's what actually matters. 1. Finished garment measurements, not body measurements. This is where most people go wrong. You need to know the exact bust, waist, and hip circumference of the finished piece you want, then add ease. For a fitted top you might add 2 to 4 inches of positive ease depending on the fabric. For a drapey linen blend you might add 6 or more. I once made a top using my actual bust measurement and it was literally unwearable because jersey knits have zero give when worked in stockinette. The workaround was simple: I started measuring finished garments from my closet that I already owned and liked how they fit, then used those numbers instead. 2. Gauge swatch that matches your actual setup. Not the one you knit on US 6 needles with worsted weight yarn while standing at the kitchen counter. The one you knit on the needles and yarn you're actually going to use, washed and blocked the way you plan to treat the finished piece. Knit at least 6 by 6 inches. Measure the center 4 inches. If your gauge is off by even half a stitch per inch across a 40-inch chest panel, you're looking at an 8-stitch discrepancy that will make the garment significantly too wide or narrow. I learned this the hard way with a merino laceweight cardigan that shrank two full sizes after blocking because I'd gauged on dry, unblocked yarn.
3. Pattern or calculation method chosen before you cast on. This sounds obvious but I've lost count of the tops I started with just a vague idea of "raglan from the top down." You need to decide whether you're working top-down or bottom-up, raglan or set-in sleeve or sleeveless, and have the math worked out. For a top-down raglan, you need your neck circumference divided into front, back, and sleeve sections with the raglan increase amounts factored in. Write it down. I keep a spreadsheet now. The first thirty tops I made I was guessing at the math and guessing wrong about half the time. 4. Yarn quantity calculated with a buffer. Most pattern yarn estimates are optimistic. They assume you're working at the exact recommended gauge with no mistakes, no variations in tension between sections, and no last-minute size adjustments. Add 10 to 15 percent to whatever the pattern says. If a pattern calls for 900 yards and you're using a yarn where the batch dye lot might vary slightly, get 1000. I once ran exactly to the last yard of a hand-dyed top that had just hit the armhole shaping and had to order more from another lot. The color shift was subtle enough that it passed inspection but only because nobody else was looking at it closely. 5. Needle size flexibility. Have your planned needle size, but also have one size up and one size down available. Sometimes the yarn behaves differently than expected. Sometimes your tension varies between sections. I keep a small envelope with spare needles in common sizes nearby while I work. When I hit the underarm and realize the fabric is too dense and stiff, switching to the larger needle saves the section instead of frogging three hours of work.
6. Stitch markers that won't slip. Ring markers for stitch counts. Locking markers for beginning of round. Split ring markers for raglan lines. Cheap plastic slide markers will migrate during washing and you'll lose your increases. I use a mix of different colored ring markers so I can tell at a glance which line is which without stopping to count. Color coding matters more than you'd think when you're twenty rows deep and tired. 7. A plan for seams and finishing. Do you want invisible seams or will you leave it seamed? Kitchener stitch for the underarm and sleeve seam gives a completely different result from whip stitch or mattress stitch. The shoulder seam on a top-down raglan is also something you need to think about early. I used to ignore this and end up with ugly ridges at the shoulder that dug into my collarbone. Switching to mattress stitch for the shoulder and Kitchener for the underarm changed how the garment sat on my body more than anything else I did. 8. Wash and care considerations baked into the design. If you're making a garment that will be machine washed, pick yarn and stitch pattern accordingly. Hand-wash-only laceweight won't survive a weekend of actual wear and care. I've made tops in superwash merino that I throw in the wash and they come out fine. I've also made beautiful alpaca tops that I hand wash and lay flat and still end up stretched out and misshapen after a few wears. Know what your yarn actually does before you commit to a whole top.

9. Fit marked in your notes. For top-down construction, note where the armhole shaping should start and where the body begins. For bottom-up, note where the sleeve cast-on happens and what the underarm increase strategy is. I write these checkpoints in the margin of my pattern or in my spreadsheet with row numbers. Without them you're just knitting and hoping you hit the right spot when you get there. I once knit an entire front panel before realizing I'd missed the armhole shaping row because I'd lost my place and didn't have a marker for it. Two hours gone. 10. A timeline that accounts for blocking. Blocking isn't optional. It's not a nice-to-have. It's where your gauge finally settles into what it actually is. Factor in drying time, especially for natural fibers. In humid weather a wool top can take two days to dry flat. I schedule my finishes around this now. If I want a top done for a specific date, I start blocking at least four days before I need it. This also means you should try the garment on after blocking, not before, because the dimensions can shift by an inch or more depending on the fiber. The list isn't perfect. There are projects where skipping one of these steps worked out fine. A simple sleeveless tank in acrylic yarn where I eyeballed everything and it turned out acceptable. But for anything you care about wearing regularly, following this sequence cuts down on the kind of headaches that make people quit knitting entirely. The real bottleneck most people hit isn't the knitting itself, it's the planning. Get the plan right and the knitting is just the tedious part that takes time. Get the plan wrong and the knitting becomes frustration wrapped in tedious.
