Textures and Tassels Blanket 15: Bertha Square

Easy Crochet Square Pattern by Underground Crafter

This simple 6” (15 cm) motif starts with a mitered square and is textured by stitches worked into the back loop.

The Textures and Tassels Blanket is a mystery crochet along for a throw-sized blanket worked in a combination of motifs and rows. Borders are crocheted in the round and the blanket is finished off with tassels. (Optional, of course, if you don’t like tassels.) New clues will be released on Fridays through December 10, 2021.

Finished Size

  • Throw Blanket.

Materials

  • Lion Brand Heartland yarn (Solids: 100% acrylic, 5 oz/142 g, 251 yd/230 m; Tweeds: 94% acrylic/6% rayon, 4 oz/113 g, 200 yd/183 m): 14 skeins in your choice of colors, or approximately 3,320 yards/3,036 meters in any medium weight yarn.
  • Clover Amour US Size I-9/5.5 mm crochet hook, or size that matches gauge or you prefer using with medium weight yarn.
  • Clover Tassel Maker in Large or Small, or the bundle of both sizes (optional, but very helpful if you plan to finish your blanket with tassels).
  • Clover Quick Locking Stitch Marker set (optional, but helpful for marking the front and holding pieces together for seaming).
  • Clover Chibi yarn needle.

Gauge

  • See individual clues for gauge information.

Textures and Tassels Blanket Pattern Notes

  • The Textures and Tassels Blanket Blanket is constructed using a combination of motifs and rows. Borders are crocheted in the round. New “clues” will be released on Fridays during 2021.
  • I am using 3 colors for my version of the blanket: Lion Brand Heartland yarn in 178 Pinnacles (CA), 195 Biscayne (CB), and 350 Mount Rainier Tweed (CC). This is a “dye lot” yarn, so be sure to get enough of each color you plan to use so that the colors match. If you substitute a “no dye lot” yarn, the dyes are consistent between batches so you can order additional yarn as needed and the colors will 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.
  • 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.
    • Fiber Flux has a helpful video tutorial for crocheting over your yarn tails as you work here.
    • Stitches n Scraps has helpful video and photo tutorials for 3 ways of weaving in ends here. I use the yarn (tapestry) needle method.
    • 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.
  • Color changes are only suggestions. You are welcome to change colors more or less often.

Abbreviations Used in This Pattern

  • BL – back loop only – Lion Brand has a helpful video tutorial for identifying the back loop here.
  • CA – Color A
  • ch – chain
  • dc – double crochet
  • rep – repeat
  • Rnd(s) – Round(s)
  • RS – right (front) side
  • sc – single crochet
  • sl st – slip stitch
  • sp – space
  • st(s) – stitch(es)

Notes for Part 15

  • Gauge: Motif = 6” (15 cm) in pattern.
  • You will need a locking stitch marker or piece of scrap yarn for this square.
  • Ch 1 at beginning of Rounds and sl st joins do not count as a stitches.
  • Color changes are only suggestions. You are welcome to change colors more or less often. For this section, my Color A is Lion Brand Heartland yarn in 178 Pinnacles.
  • If you decide to change colors in this square, you will find the instructions for this multicolor mitered square pattern helpful.
  • Rows 1-3 are worked flat in rows, turning at the end of each Row. Your final repeat of Row 3 will be the right (front) side of the project and then you will begin working in Rounds.
