Materials Needed

Before you begin, gather the following supplies. This project is perfect for using up small amounts of worsted-weight cotton yarn in your stash.

• Yarn: Worsted weight cotton or cotton-blend yarn in 6 colors (e.g., red, orange, yellow, green, blue, purple) – approximately 20g of each
• Needles: US 6 (4.0 mm) knitting needles (straight or circular for magic loop)
• Gauge: 20 stitches and 28 rows = 4 inches in stockinette stitch (after blocking)
• Notions: Tapestry needle for weaving in ends, scissors, stitch markers (optional)

Step-by-Step Instructions

This cozy is knitted flat and seamed, making it perfect for beginners. It uses a simple slip-stitch colorwork technique to create a spiral rainbow effect. Follow along carefully, and you'll have a stunning mug cozy in no time.

Abbreviations

• CO: cast on
• K: knit
• P: purl
• Sl: slip stitch purlwise
• K2tog: knit two together
• St(s): stitch(es)
• RS: right side
• WS: wrong side

Step 1: Cast On

With Color A (red), CO 36 stitches. Leave a 6-inch tail for seaming. This tail will be used later to sew the side seam of your cozy.

Step 2: Ribbing (Rows 1-6)

This ribbed edge will create a snug, stretchy top and bottom for your cozy.

• Row 1 (RS): *K2, P2*; repeat from * to end.
• Rows 2-6: Repeat Row 1. (You will have 6 rows of ribbing.)

Step 3: Begin Spiral Colorwork (Rows 7-30)

Now you'll work in stockinette stitch (knit on RS, purl on WS) while introducing the other colors in a spiral pattern. Each color section will be 4 stitches wide, and you will shift the starting point of each color by 1 stitch every 4 rows to create a diagonal drip effect. This is the heart of the Prism Drip design.

Row 7 (RS): With Color A, K4; join Color B (orange), K4; join Color C (yellow), K4; join Color D (green), K4; join Color E (blue), K4; join Color F (purple), K4; then with Color A again, K4; with Color B, K4; with Color C, K4. (Total 36 sts)

Row 8 (WS): With Color C, P4; with Color B, P4; with Color A, P4; with Color F, P4; with Color E, P4; with Color D, P4; with Color C, P4; with Color B, P4; with Color A, P4. (This reverses the order, but you are simply purling each color section as it appears.)

Row 9 (RS): With Color A, K3; with Color B, K4; with Color C, K4; with Color D, K4; with Color E, K4; with Color F, K4; with Color A, K4; with Color B, K4; with Color C, K5. (Notice the first section is now 3 sts, and the last is 5 sts – this shifts the spiral.)

Row 10 (WS): Purl each color section as it appears, following the same stitch counts as Row 9, but in reverse order (starting with the last color section).

Row 11 (RS): With Color A, K2; with Color B, K4; with Color C, K4; with Color D, K4; with Color E, K4; with Color F, K4; with Color A, K4; with Color B, K4; with Color C, K6.

Row 12 (WS): Purl as established.

Row 13 (RS): With Color A, K1; with Color B, K4; with Color C, K4; with Color D, K4; with Color E, K4; with Color F, K4; with Color A, K4; with Color B, K4; with Color C, K7.

Row 14 (WS): Purl as established.

Row 15 (RS): With Color A, K0 (drop it); with Color B, K5; with Color C, K4; with Color D, K4; with Color E, K4; with Color F, K4; with Color A, K4; with Color B, K4; with Color C, K7. (Now Color A is gone, and Color B has 5 sts.)

Rows 16-30: Continue this pattern, shifting the starting point of the first color section by 1 stitch every 4 rows, and dropping the first color when it reaches 0 stitches. Add a new color at the end when needed to keep 6 colors active. You will have a beautiful diagonal spiral.

Pro Tip: To keep your yarns from tangling, wind each color into its own small ball or use bobbins. Carry the yarn loosely across the back of the work to avoid puckering.

Step 4: Top Ribbing (Rows 31-36)

Finish the top edge with matching ribbing to mirror the bottom.

• Row 31 (RS): With the last color used, *K2, P2*; repeat from * to end.
• Rows 32-36: Repeat Row 31.

Step 5: Bind Off

Bind off loosely in pattern (knit the knits and purl the purls). Cut yarn, leaving a 6-inch tail. Binding off loosely ensures the top edge remains stretchy enough to slide over your mug.

Step 6: Seaming

Fold the cozy in half with RS together. Use the tails to whipstitch the side seam from the bottom ribbing to the top ribbing. Weave in all ends securely. Make sure your seam is neat and lies flat.

Step 7: Finishing

Block gently to even out the stitches. Slide onto your favorite mug and enjoy the warmth! Blocking will help the colorwork lay flat and the stitches look uniform.

Tips for Success

• Color Choices: Feel free to substitute your own color palette. The spiral effect works beautifully with any six colors that transition well together.
• Yarn Substitution: If you don't have cotton, any worsted-weight yarn will work. Just be sure to check your gauge.
• Gauge Matters: Always knit a swatch first. If your cozy is too loose or too tight, adjust your needle size accordingly.
• Weaving Ends: Weave in ends as you go to save time at the end. Use a tapestry needle and weave on the wrong side of the work.

This Prism Drip Coffee Cozy is a delightful project that combines practicality with artistic flair. It makes a wonderful gift for coffee lovers, and the spiral colorwork is sure to spark conversation. Happy knitting!
