Gauge & Tension Calibration

Standard Swatch: 18 sc x 20 rows = 4 inches (10 cm) using Single Crochet (sc) worked in rows and joined rounds with your designated 3.5 mm (US E/4) hook.

Consistent tension with your 3.5 mm hook keeps stitches dense so stuffing stays completely hidden.

Important Pattern Notes

  • Strict 3.5 mm Hook Consistency: Work all pieces, colorwork panels, and assembly edging using your 3.5 mm (US E/4) crochet hook for uniform stitch density.
  • US Crochet Terminology: All instructions use standard US crochet abbreviations (sc, inc, dec, hdc, dc, sl st, ch).
  • Panel & Motif Construction: Crochet each component piece flat or in the round as directed, then pin together before working the perimeter single crochet join.
  • Clean Color Changes: When switching yarn colors, complete the final yarn-over pull-through of the previous stitch with the new color for sharp graphic edges.

Hello! Popping in today with some crochet décor! I like to change things up every now and then from my usual amigurumi projects; a quick and satisfying project like a throw pillow is usually just the ticket. Enter these Colour-Block Geo Thr

As the name suggests, the Tunisian Simple Stitch is perhaps the easiest stitch to learn so don’t sweat it, even if you’re a Tunisian beginner! This pattern does, however, incorporate colour changes, so, rather than reinvent the wheel, I am

If you are not feeling the pillow vibe, you could also use just one panel to make a lovely wall-hanging and you could add some fringe to the bottom, or try adding a wide border to turn it into a squishy rug! Also, you don’t need to use hue+

One final note: I only purchased one skein of each colour, so in order to ensure the back panel used the exact same colours as the front panel, I inverted colours ‘A’ and ‘C’, as shown below. Colour ‘B’ stayed in the same position for both

Frequently Asked Questions

Frequently Asked Questions

Clear answers to common gauge, yarn weight, and technique inquiries

What hook size should I use for the Modern Color-Block Geometric Cushion?

This pattern is calibrated for a single 3.5 mm (US E/4) crochet hook throughout every step. Using the same 3.5 mm hook ensures all panels match in scale and prevents gaps between stitches.

Is the Modern Color-Block Geometric Cushion pattern suitable for beginners?

Yes! Rated Intermediate, it uses foundational stitches (chain, single crochet, simple increases and decreases) paired with clear step-by-step construction photos.

How do I keep the edges flat when joining two panels together?

Clip the front and back panels together at the corners and midpoints with locking stitch markers before crocheting around the perimeter, and stuff progressively in small tufts.

Can I use cotton yarn instead of acrylic yarn?

Absolutely! A smooth worsted or DK cotton yarn worked with your 3.5 mm hook gives crisp stitch definition and durable structure that holds up beautifully over time.

How do I wash and care for my finished Modern Color-Block Geometric Cushion?

Spot clean gently with cool water and mild wool wash, or hand wash lightly and reshape flat on a dry towel away from direct heat.
