The Design

It seems like I am always searching for the perfect, everyday tee. Very rarely do I come across one that is just ~perfect~ and when I do, I buy a handful!

In my mind, a perfect t-shirt needs to have a good neckline. I prefer crewneck but not a tight crewneck.

I also want it to be well fitting. I find that around 4″ of positive ease looks best on my body and gives that fitted but not tight look.

Finally, it NEEDS to be comfortable. Most importantly, the fabric has to be soft and cool with nice drape. I knew I needed to use this yarn from Lion Brand!

The Knitting Pattern

Another thing I was certain about when designing this pattern is that I wanted it to be fun and easy to make! Summer is an easygoing time for relaxing and I wanted this pattern to be one that was enjoyable to make for this time of year.

This pattern is worked primarily in-the-round from the top, down. At the beginning, you will work a couple rows flat to shape the front neckline so that it sits a bit lower than the back neckline. Then, you will join to work in the round and shape the shoulders, body, and sleeves.

Yarn and Materials

The yarn I chose for this sweater is Lion Brand Coboo. This is my number one favorite yarn of all time. Its a true DK weight and is made of 50% bamboo and 50% cotton. These natural materials make a yarn that is breathable, cool, and amazingly soft.

If you are interested in using this exact yarn, you might want to check out the knit kit which contains all the yarn needed to make this top and a free copy of the pattern!

I will note that this yarn is plied and has a tendency to ‘split’ between your needles. I personally don’t find this to be an issue but if this is something that bothers you I have some great yarn substitutions listed below.

Yarn Substitutions

Some other yarns that I recommend for this knit t-shirt are:

  • Truboo from Lion Brand: a 100% bamboo yarn similar to Coboo but without the cotton! This yarn is a bit shinier and silkier than Coboo.
  • Comfy Cotton Blend: another favorite, this yarn is an acrylic cotton blend that I’ve used and loved many times!
  • CotLin from KnitPicks: this yarn is a cotton, linen blend so its very cooling and perfect for warm weather. Its not quite as soft as some of the others but I still love it because it has that high-end linen feel
  • Swish DK: a 100% merino wool yarn, perfect if you don’t want to use cotton but still prefer to use natural fibers! Just note, this yarn is wool so its a bit warmer than the other options.
  • Comfy Worsted: this yarn is labeled as a worsted weight but I strongly think that it is more of a DK weight. I am always impressed with this yarn and how unbelievable soft it is! Also check out Comfy Color Mist, the same yarn just with speckled colors instead of solids.

BO using a 6 stitch I-Cord bind off.

An I-Cord Bind Off gives this simple t-shirt a beautiful finished edge! This is my favorite tutorial for the i-cord bind off:


Using double pointed needles or shorter circular needle, slip the 62, (70, 84, 94, 104), (114, 126, 136, 148) sts set aside for a sleeve onto your needle. Pick up and knit 9 sts at the underarm, k around arm opening even in stst until sleeve measures 1.5”. End the final row at the center of the underarm.
