Spectrum Stitch Crochet Swoncho | Part 3 | Prism Make-Along 2025 Free Pattern
Welcome back, Bestie! 🎉 Part 3 of the Spectrum Stitch Swoncho is here, and today you’ll be working through Charts 3 and 4 of this bold, beautiful yoke.
This week is all about keeping your stitches even, managing your floats with confidence, and making sure your work lays flat as the fabric grows. You’ll also want to stay mindful of your yarn’s fiber content—we’re sharing a few important tips for gentle steam blocking if your yarn allows.
Let’s keep those stitches moving and that colorwork glowing! ✨

🎨 Charts 3 & 4: Let the Color Flow
These next two charts build on the structure and rhythm of your previous rounds. They introduce new color combinations and bring symmetry and visual movement to your yoke.
Here’s what to keep in mind:
- Take your time reviewing the chart before starting—look for repeats and float spans
- Stay consistent with your stitch height in split single crochet
- Use stitch markers if it helps you track chart sections
- If you’re customizing your color palette, double-check your contrast so motifs remain clear
🧶 Maintain That Gauge
Stranded colorwork can easily tighten your tension, especially with more color changes and longer floats.
✅ Here’s how to stay on track:
- Continue aiming for 4 stitches per inch in split single crochet
- Check gauge frequently throughout the round—not just after
- Adjust your hook if needed—sometimes going up one size for a section can help
- Keep floats relaxed and avoid pulling them tight behind your stitches
💨 Steam Blocking: Proceed With Caution!
Lightly steam blocking as you go can help your piece lay flat and prevent buckling—but only if your yarn allows it.
⚠️ Read this before steaming:
- Test steam blocking on a swatch first, especially with synthetic fibers
- Acrylic yarn can “go limp” or lose its bounce if exposed to too much steam
- Natural fibers (like wool) tend to steam block beautifully—but still test first
- Always pin and shape carefully, and never press the iron directly onto the fabric
When in doubt? Skip the steam for now and gently shape with your hands.
✂️ Weave In Your Ends as You Go
Color changes bring ends—and it’s tempting to save them for the end. But weaving them in as you go makes your life easier and helps clean up your joins!
Here’s why it matters:
- Ends can help close the gap at the beginning of the round
- It keeps your fabric smooth and reduces bulk
- You’ll avoid that “dreaded pile” of tails at the finish line
- It helps maintain your garment’s structure over time

NOTES
- Project is worked in joined rounds of split single crochet. Join is made by removing hook from free loop, insert hook under top 2 loops of first st from back to front, replace free loop and pull through.
- Place marker in first stitch throughout project.
- Change color when there are 2 loops left on the hook of the previous color.
- Sweater is stranded color work not tapestry colorwork. Be sure to keep your floats loose and not too tight. If they are tight you will reduce the elastic nature of the fabric and your project might not fit you.
- Do not crochet over the floats or the fabric will become too thick!
- It is easy to tighten up your split single crochet stitches, be sure to pull up a longer loop to keep your stitches from getting too small. If your stitches are too tight, you will not see the colorwork as clearly and it will be difficult to insert your hook. You can always go up a hook size or two to keep your stitches from getting too small.
