To change color, work last stitch of old color to last yarn over; yarn over with new color and draw through all loops on hook to complete stitch. Carry color not in use up side of piece until next needed. Cover carried strands when joining front and back.
FRONT AND BACK (make 2 pieces)
Color Sequence: Work 3 rows with A, [2 rows with B, 2 rows with C, 2 rows with D, 2 rows with A] 2 times.
With A, make an adjustable ring.
Row 1: Ch 3 (counts as dc here and throughout), (dc, ch 3, 2 dc) in ring, turn—4 dc and 1 ch-3 sp. Pull gently, but firmly, on tail to tighten ring.
Row 2: Ch 3, sk first dc, working in back loops only, dc in next dc, (2 dc, ch 3, 2 dc) in corner ch-3 sp, dc in last 2 dc, turn—8 dc and 1 ch-3 sp.
Row 3: Ch 3, sk first dc, working in back loops only, dc in each dc across to corner ch-3 sp, (2 dc, ch 3, 2 dc) in ch-3 sp, dc in each dc across; change to B in last st, turn—12 dc and 1 ch-3 sp.
Rows 4–18: Repeat Row 3, continue to change color as in Color Sequence—72 dc and 1 ch-3 sp.
Row 19: With A, ch 3, sk first dc, working in back loops only, dc in each dc across to corner ch-3 sp, (2 dc, ch 1, 2 dc) in ch-3 sp, dc in each dc across; change to D in last st, turn—76 dc and 1 ch-1 sp.
Round 20: With D, working in back loops only, sc evenly around all edges of piece, working 3 sc in each corner; join with sl st in first sc. Fasten off.
Join Front and Back, and Edge Pillow
Hold WS of front and back together. Working through both thicknesses, join yarn with sl st in any corner.
Round 1: Working through both thicknesses, ch 1, sc evenly spaced around 3 edges of pillow, working 3 sc in each corner; slip pillow form into cover; sc across remaining edge; join with sl st in first sc, do not turn.
Round 2: Ch 1, rev sc in each sc around. Fasten off.
Using yarn needle, weave in all ends.
Tassels (make and attach 4)
Wrap D around a 5"/12.5cm piece of heavy cardboard, 30 times. Thread an 8"/20.5cm length of yarn under the wraps at one end of the cardboard and tie a knot. Cut the other end of the wraps. Tie another length of yarn around the tassel about 1"/2.5cm below the top knot. Draw the ends into the center of the tassel. Use ends of the top knot to tie tassel to one corner of pillow and weave in ends. Trim ends.
