Diamond Crochet Sweater Free Pattern

Sharing is caring!

Another Beautiful Project! This Diamond Crochet Sweater Free Pattern is now part of the Life and Yarn Blog and I am so excited to finally release this trendy collared turtleneck pullover sweater to you! This intermediate level crochet pattern uses back and forth rows and in the round crochet to create a beautiful knit-look sweater. Although I have classified this as an Intermediate Sweater, I believe a determined beginner could make it as well. Just follow each set of instructions step by step and take your time! Keep scrolling to use the free crochet pattern in this blog post or click the button below for an affordable pdf!

Design Story and Inspiration

Just like my Mellowspun Sweater, I wanted this Diamond Crochet Sweater Free Pattern to be something that myself and others would actually wear. I definitely think I have been achieving the “so good, it looks store bought” vibe with these last two designs! Another thing this Collared Pullover Crochet Sweater has in common with Mellowspun is that I completed it a year ago! Now that I think about it, my two best designs seem to have come about during the moving madness. I really do work well under pressure! As the weather is finally starting to get chilly here in Florida, I think it is about time that I can wear this sweater out without sweating! Yay!

About the Yarn

One of my favorite go-to yarns is Mary Maxim’s Irish Tweed! I LOVE this yarn is an understatement. My only complaint is that it only comes in the one color that I used to make the pullover turtleneck sweater. However, a great sub from is Mary Maxim Alpaca Tweed that comes in 12 beautiful colors! What I love about Irish Tweed is that is wears and washes really well! It is super soft, and has great stitch definition! The photo below is from when I used this same yarn to make my cozy alpine throw pillow!

Also, right now you can use code YayYarn to get 15% of of 5 or more skeins of ANY yarn on Mary Maxim!

Pattern Notes

  • Ch 1 and ch 2 do not count as stitch. 
  • “sc 1” means to single crochet in the next stitch. 
  • “sc 2” means to single crochet in each of the next 2 stitches. 
  • “2 sc” means to single crochet twice in the next st to create an increase. 
  • FPtr sts count as stitches. You must skip the corresponding stitch on previous row, working first leg around previous FPtr and sk 3sc in previous row to work second leg around the fourth sc.
  • Single crochet in the round can give you a much different gauge than working in back and forth rows. When you begin working your sleeves be sure to check your gauge again since the hook size that worked for your body may not work for your arms. Adjust accordingly.
  • Skill Level : Intermediate

You will be working in the round with right sides facing you to create a knit-like look. There will be no turning or joins, the arms are worked in continuous rounds so no seams are seen in the sleeves.

  • Note: Check your gauge again here. Working single crochet in the round can create a  different gauge due to tension. You may need to go up a hook so that your arms are not too tight. 
  • Note: Average is 3 sts per row end, placing 2 sc in each dc row end and 1 sc in each sc row end. Confirm counts and adjust as needed.
