Welcome to Week 1 of the Stitch Adventure Blanket! In this post, we will crochet the foundation chain, foundation row, and our first stitch pattern, the crochet shell stitch. This is a very simple version of an alternating crochet shell stitch, where increases are placed decoratively to create arches. This pattern is best highlighted using at least 2 different colors.

Stitch Adventure Blanket 1

Crochet Shell Stitch Pattern by Underground Crafter

Crochet shell stitches use increases decoratively to create arched shells. This pattern alternates the position of the shells on every row and is best highlighted in 2 or more colors.

The Stitch Adventure Blanket is a mystery crochet along. Unlock the mystery of this crochet sampler blanket, row by row, on Saturdays in 2020.

Stitch Adventure Blanket Pattern Notes

  • The Stitch Adventure Blanket is constructed in one piece in rows with borders added in the round. New “clues” will be released on Saturdays during 2020.
  • I am using 5 colors for my version of the blanket: Red Heart With Love yarn in 1001 White, 1012 Black, 1401 Pewter, 1803 Blue Hawaii, and 1939 Papaya.
  • Red Heart With Love is a “no dye lot” yarn, meaning that the dyes are consistent between batches so you can order additional yarn as needed and the colors will match. If you substitute a “dye lot” yarn, be sure to get enough of each color you plan to use so that the colors match. You can use as many or as few colors as you like for your version. I recommend at least 2 colors to show certain stitch patterns.
  • I change colors in the last yarn over (yo) before the next color is used, usually in the last yo of the row.
  • Whenever possible, I recommend crocheting over your yarn tails as you work. Sometimes, a stitch pattern will be too lacy to effectively crochet over your yarn tails. In that case, I recommend weaving in ends.
    • Because the border will be crocheted in the round over the unworked sides of rows, when changing colors often you can carry your yarn tails up the side of your work. AllFreeCrochet has a helpful video tutorial for carrying your yarn tails up the side of your work here.
  • Stitch multiples for individual stitches vary. However, the blanket rows are crocheted in multiples of 24 stitches, + 2 stitches.
  • Color changes are only suggestions. You are welcome to change colors more or less often.
  • Unless otherwise noted, stitch count remains the same throughout the blanket as your stitch count at the end of Clue 1 Foundation Row – 122 (122, 194, 218, 266, 242 sts).

Abbreviations Used in This Pattern

  • CA – Color A
