You'll need a 90 (115, 280, 600, 920, 1295, 1920, 3710, 5075, 5860, 6640, 6880) Yards of Worsted Weight Yarn - I'm using Lion Brand Pound of Love in the Denim, Olive and Pumpkin Spice colorways, an H8/5mm Crochet Hook, and a Tapestry Needle.
Material Notes:
Shop Lion Brand Pound of Love in my Yarn Shop: yarncraftsandcoffee.com/product/lion-brand-pound-of-love-yarn
Depending on the project you’ll be working with this square, the yarn options can vary, but they’re practically endless. Feel to use your favorite worsted weight yarn, but I’ll provide some ideas:
For things like an afghan, scarf and shawl, acrylic yarn, like the Pound of Love I used, is a good choice. For a cozier option, go with a wool blend, like Lion Brand Wool Ease or Berroco Vintage. For a warm weather option, a cotton blend, like Berroco Modern Cotton or Lion Brand Made with Love are great choices.
For things like a tote bag, washcloth or table runner, a 100% cotton yarn, like Circulo Natural Cotton Maxcolor 4/6, WeCrochet Dishie or Queensland Coastal Cotton is what I would recommend. These are nice, durable options that wear and machine wash well and are also colorfast (not all cotton yarns are).
If you want to treat yourself to an ergonomic crochet hook, I like using the clay hooks from these two shops on Etsy:
- Shop BronzeShepherdStudio: tidd.ly/435FfYY
- Shop SiennasBowtique: tidd.ly/3IqAMGD
Time Spent:
I worked the 16" size in about two and a half hours.
Goal Measurements: Actual Measurements with Border - Width by Height:
- 4": 3 7/8"
- 6": 5 7/8"
- 8": 8 1/2" by 8"
- 10": 10" by 10 1/8"
- 12": 10 1/8" Wide by 10 1/4" Tall
- 14": 14 1/4"
- 16": 16 1/4"
- 18": 18 1/8" by 18 3/8"
- 20": 19 7/8” by 19 3/4”
- 22": 21 7/8" by 21 3/4"
- 24": 24 1/8" by 23 7/8"
- 27": 27 1/8" by 27 3/8"
Gauge (Not essential):
In Pattern, 14 HDC by 12 Rows = 4" Wide by 4 1/8" Tall
Note: If you are measuring a swatch that is only 14 HDC wide by 12 rows tall, it will measure slightly larger. If working a swatch, I recommend working at least 20 stitches by 18-20 rows, but a swatch is not necessary for this project unless the finished size is essential for your project.
When working the pattern, the border will add about 1/2" to the width and 5/8" to the height. After working at least 6-8 rows, you can measure the width, add in the border, and you will know if the finished size will be where you want it to be. The height is even easier to see as you can measure as you go, and stop when you get close to your desired height making sure to figure in the border.
