Step-by-Step Pattern

Preparation

Start by selecting your rainbow yarn colors in sequence (e.g., red, orange, yellow, etc.).
Begin with Red yarn for Round 1.

Round 1 – Foundation Row:

Make a slip knot and ch 9. (This forms the base chain for your rainbow curve.)
- Chaining tightly will keep the applique edges neat.
Skip the first chain from the hook, and make 1 sc into the second chain.
For next 6 chains, work 2 sc into each chain (increase).
- Repeat: Insert hook into chain, pull up a loop, and complete the single crochet twice.
Into the last chain, make 1 sc only.
Fasten off Red yarn, and pull the ends tightly to close the row.

You should now have 14 stitches in total:
1 sc at the beginning, 12 sc increases, and 1 sc at the end.

Round 2 – Adding Orange Yarn:

Join Orange yarn into the first stitch of Round 1 using a sl st.
Ch 1, and make 1 sc in the same stitch.
Work 1 sc in each stitch across the row.
- By the end of this row, you should still have 14 sc stitches.
Fasten off, weave in the Orange yarn ends.

Round 3 – Adding Yellow Yarn with Increases:

Join Yellow yarn into the first stitch of Round 2 using a sl st.
Ch 1, and make 1 sc in the same stitch.
Work the following pattern across the row:
- 2 sc into the next st (increase), 1 sc in the next st.
- Repeat this pattern across the row (1 increase followed by 1 sc).
You should have 21 stitches by the end of the row.
Fasten off, and secure the Yellow ends.

Round 4 – Adding Green Yarn:

Join Green yarn into the first stitch using a sl st.
Ch 1, and make 1 sc in the same stitch.
Work 1 sc in each stitch across the row.
- By the end of this row, the stitch count remains 21 sc.
Fasten off Green yarn.

Round 5 – Adding Blue Yarn with Increases:

Join Blue yarn into the first stitch using a sl st.
Ch 1, and make 1 sc in the same stitch.
Across the row, alternate the following pattern:
- 1 sc, 1 sc, 2 sc (increase).
- Repeat 1 sc, 1 sc, inc two more times.
At the end of the row, switch back to 1 sc per stitch, completing 27 stitches total.
Fasten off Blue yarn, and securely weave in ends.

Round 6 – Adding Indigo Yarn (Same as Round 5):

Follow Round 5 instructions. Work 1 sc, 1 sc, inc, and repeat the pattern across the row.
You will have 33 single crochet stitches in total for this round.
Fasten off Indigo yarn.

Round 7 – Adding Violet Yarn with Final Shaping and Increases:

Join Violet yarn into the first stitch using a sl st.
Ch 1, and make 1 sc in the same stitch.
Across the row, use the following pattern to shape the upper curve:
- 1 sc, 1 sc, 1 sc, inc.
- Repeat 3 sc, inc across.
By the end of this row, you’ll have 41 stitches.
Fasten off Violet yarn.

Finishing Touches

Weave in Ends: Use the tapestry needle to weave yarn tails into the corresponding color sections. Insert the needle under the back loops only for invisible finishing.
Optional Decoration: Add tassels, fringe at the ends, or a small sun applique to create a themed display.

Customization

Size Variations:
- For larger rainbows: Increase the base chain in Round 1 and repeat the increase rows proportionally. For example, chain 12 and repeat 2 sc increases across.
- For smaller rainbows: Work fewer rows or use thinner yarn (like fingering or sport-weight yarn).
Color Theme Alternatives:
- Use pastel rainbow colors for soft, muted tones.
- Create monotone versions of the rainbow for a decorative motif (e.g., shades of blue).

Tips for Success

Block the finished applique gently to flatten edges and ensure neat shaping.
Keep your tension consistent across increases to ensure a smooth curve.
For a seamless look, change colors using the invisible join technique for color changes in crochet.

Conclusion

The Crochet Rainbow Applique is a timeless, cheerful decorative piece ideal for accessorizing blankets, clothing, or other projects. Its easy, repetitive rows cater to intermediate crocheters but offer enough variation to keep the work engaging.

Pattern Corrections (if needed)

If your curve isn’t forming properly:

Double-check your stitch counts per row for consistency.
Ensure increases are spaced evenly across rows to maintain symmetry.
