Spectrum Stitch Crochet Swoncho | Part 4 | Prism Make-Along 2025 Free Pattern

You're flying through the Prism Make-Along—and Part 4 of the Spectrum Stitch Crochet Swoncho is here! 🎉 This week, we’re diving into Charts 4 and 5, adding even more colorful complexity to your yoke as the swoncho continues to grow.

These next two charts are where the pattern really starts to pop, and your color story begins to unfold in dramatic ways. Let’s keep those hooks moving and your fabric smooth and strong!

🎨 Charts 4 & 5 – Time to Build the Drama

This week’s charts expand on your previous motifs with increased color interaction and visual weight. Don’t be surprised if this becomes your favorite section yet!

Here’s what to watch for as you work through Charts 4 and 5:

  • The colorwork patterns become more detailed and dynamic
  • Float management becomes even more important for smooth fabric
  • If using a custom color palette, double-check contrast as new color pairings emerge

💡 Split single crochet works best when stitches are stacked cleanly—don’t forget to insert your hook between the “legs” of the stitch, not under both loops like a regular single crochet.

📏 Keep Checking Your Gauge

As always with stranded colorwork, it’s important to stay consistent:

  • Your target gauge is 4 stitches per inch in split single crochet
  • Check your gauge around the full circumference—sometimes tension shifts slightly near the join
  • If your fabric is starting to pull or shrink, rip the work back and go up a hook size
  • Keep your floats loose and even behind longer color spans
  • Increase rounds are often crocheted a bit too tight–so make sure you keep those loose.

Tension consistency = a better fit and a swoncho you’ll love wearing!

💡PRO TIP: before continuing further, make sure your swoncho lays in a flat circle. This will help you quickly see if you’re making the stitches too tight. 

🚨If your swoncho doesn’t lay flat, you can try steam blocking a bit to help it flatten out (BUT BEFORE YOU DO SEE THE CAUTION ABOUT STEAM BLOCKING BELOW). Or you can rip out each round until it does lay flat then proceed with looser stitches. 

If your piece doesn’t lay flat, then it might look cone like when you put it on. Go ahead and try it on and see. 

It should look like this:

💨 Light Blocking (While in Progress!)

As your yoke grows, we want to prevent any buckling or puckiner in the fabric. If you notice this happening to your project, don't you worry that something’s wrong, try a gentle steam block while the piece is still in progress.

Here’s how to safely steam block your crochet colorwork:

  • Lay your swoncho flat on a towel or blocking surface
  • Hover a steamer or steam iron a few inches above the fabric—do not press down
  • Gently shape the fabric with your hands as you steam, focusing on areas with rippling
  • Let everything cool and dry before continuing

⚠️ IMPORTANT: Always test steam blocking on a swatch of the same yarn first. Some fibers—especially acrylic—can go limp if over-steamed. Natural fibers usually respond better, but caution is key.

If that does not allow the fabric to lay flat, then you can rip out each round until it does lay flat then proceed with looser stitches. 

✂️ Weave in Those Ends—Now’s the Time!

Don’t let all those color changes pile up into a yarn tail nightmare. Use this section as a reminder to:

  • Weave in your ends after each chart
  • Use your tails to close the join at the beginning of your round
  • Keep your wrong side neat and manageable—future you will thank you!

SPECIAL STITCHES 

⭐Back Loop Only: This is the furthest loop to you of the top 2 loops of the stitch indicated, regardless if you are on the RS or WS.

⭐️Chain (Ch): With slip knot or free loop on hook, yarn over hook and pull through loop on hook.

⭐️Single Crochet (Sc): Insert hook into indicated stitch, yarn over and pull up a loop, yarn over and draw through 2 loops on hook.

⭐️Slip Stitch (Sl st): Insert hook into indicated stitch, yarn over and pull up a loop and draw through loop on hook. 

⭐️Split Single Crochet (split sc): Insert hook into indicated stitch between the two legs of the stitch, yarn over and pull up a loop, yarn over and draw through both loops on hook. 

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.
