Repeat and Bracket Guide

Square brackets [ ] are used for small repeats: 4dc, [2dc, 3tr, 2dc] 2 times

Asterisks *are used for repeats that include small repeats: *5dc, [1ch, 1dc] 3 times in next ch, rep from * 3 times

Round brackets ( ) are used when a string of stitches are worked into the same spot: (3tr, 3ch, 3tr) in next st

Tips and Notes

  • Weave your ends after each time you cut the yarn to avoid having to do them all at the end.
  • To get a neater result, I do not “chain up” for the first sc of the round/row. Jump straight into the first sc.

Instructions

All Motifs are worked using Yarns A-E randomly for rounds 1-11 (changing color for every round as shown in the photos). For rounds 12-14, the yarn color is specified. Motifs are joined using a slip stitch technique which will be described in the pattern. After the granny square section is complete, a chevron corner is added and a simple border completes this breezy and fun piece.

Schematic

Note: Green and red dots will be referenced later in the pattern.

Join Motifs with Flat Zipper Join

Arrange motifs as shown in Schematic. Starting in top right corner, pick up first 2 adjacent motifs, and locate back loop of right-most st on final rnd/row on both motifs. Insert hook front to back through back loop only (BLO) of the first motif, and then back to front through BLO of the second motif.

Using Yarn G, yoh, pull yarn through, then ss to join yarn (first photo below). Insert hook from front to back through BLO of next st on right hand side motif, and also front to back through BLO of next st on left hand side Motif (second photo below). Yoh, draw yarn through all 3 lps.

Next, insert hook first through BLO of next st on left hand side motif, and then through BLO of next st on right hand side Motif (third photo below). Yoh, draw yarn through all 3 lps.

Continue in this manner, alternating inserting hook first through BLO of right motif and then through BLO of left motif, yoh, draw yarn through 3 lps, then left motif/right motif, yoh, draw yarn through 3 lps. This alternating right/left, then left/right creates a very stable and straight Zipper Join which will look like the fourth photo below.

When the end of two Motifs is reached, pick up the next Motifs along the diagonal and join them in the same manner, working to the edge of the blanket. Cut yarn and finish off when the edge is reached, and work the next diagonal. Repeat along the opposing diagonals to finish joining all pieces.

Note: I learned this joining technique through a tutorial called “Completely Flat ‘Zipper’ Method” by Dedri Uys on her website LookAtWhatIMade.net.

Here are a few more photos of the Flat Zipper join in action:

Chevron Corner

Join Yarn G with ss in center of zipper join where green circle indicates on Schematic. 1sc in same spot, 39sc evenly across square, and then 40sc evenly across each of next 2 squares until spot indicated by red circle is reached. Final sc will be placed in zipper join at location of red spot. Cut yarn and weave ends. [120 sc]

Base Triangle (Make 10)

Row 1 (WS) Using Yarn H, MR, beg dc, 8dc, turn.

Row 2 (Beg dc, 1dc) in first st, 3dc, 5dc in next st, 3dc, 2dc in final st, cut yarn on all Base Triangles except for tenth one. After Row 2 of tenth base triangle is worked, do not cut yarn.

Join Base Triangles

With RS facing, hold tenth base triangle so that the bottom edge is up, 12sc evenly across bottom edge, 12sc across bottom edge of next base triangle, continue across bottom edge of all rem base triangles, do not cut yarn. [120 sc]

Tip: When working sc sts across the bottom edge, work into the sts, not around them to eliminate gaping holes.

Attach string of base triangles to blanket body

Align working yarn with green circle on schematic, matching up 120 sc, ss in BLO of first st at green circle, work Flat Zipper Join, joining all 120sc to attach base triangles to blanket body, cut yarn and weave ends.

Work chevron

Row 1 With RS facing, join Yarn I with ss in 8th st on Row 2 of first base triangle. Beg dc in same st, 5dc, dc4tog, (5dc, 5dc in next st, 5dc, dc4tog) 8 times, 6dc, turn.
