Loom Knit Baby Sweater

Loom Knit Baby Sweater

There nothing sweeter than a little baby! Unless it’s a baby wearing something you made. I love expressing my love through giving hand made gifts. Whether it’s a shower gift for an expectant friend or a donated blanket for a struggling new mom I love making baby gifts. Now I can add a loom knit baby sweater to my basket.

Sweaters can strike fear into the heart of the most experienced knitter, but this one is so easy! What makes it simple is that the pieces are all squares or rectangles. There is no armhole or neck shaping that you need to get right. If you can knit a flat panel, you absolutely CAN loom knit a sweater.

The best part about this sweater is that you could even resize it to fit an older child or adult.

Pattern Notes for the Loom Knit Baby Sweater


There are five pieces to loom knit for this pattern: 2 fronts, 1 back and 2 sleeves. Each piece is a simple square or rectangle so there’s no shoulder shaping you need to worry about. You want to make sure each piece is the correct size.

Gauge!!! Due to changing the yarn, I got a different gauge than the one listed in the pattern. This is important because if I didn’t change my cast on number my pieces would not be the correct size.

I got 5 sts per inch, but I recommend you test your gauge to make sure you get a good fit. Instead of loom knitting a separate gauge swatch just begin the front of the sweater casting on the number of pegs I list below. If your gauge is correct you can just continue your sweater!

Using a 3/8″ gauge loom and Lion Brand Heartland yarn I recommend the following:
# of Pegs to Cast On
Fronts: 25 (26, 28, 30)
Back: 50 (53, 55, 60)
Sleeves: 35 (38, 40, 45)

I recommend the Double Ewrap Cast On for this pattern. You may, however, use the cast on of your choice.

Loom Knit Baby Sweater after seaming


I know, I know! I’m talking about all the knitting topics no one likes. Gauge and seaming! They can be tricky, but I’ve got tips on seaming using the mattress stitch so your pieces will line up perfectly and smoothly.

Seaming Techniques:
Front to Back: Joins bind off edges of both pieces at the shoulder. Use the mattress stitch for a strong seam.
Sleeve to shoulder of sweater: Joins bind off edge of sleeve to side of shoulder. Use the mattress stitch for a strong seam.
Sides of sweater/sleeve: Joins up the side and across the bottom of the sleeve. Use the Bickford seam for a less bulky finish.

Loom Knit Baby Sweater adding trim in blanket stitch


Topstitch the cuffs and around the front opening of the sweater in a contrasting color to finish. While you can use any embroidery technique for finishing the edges I recommend the blanket stitch. It is very simple to do and adds a beautiful smooth edging.


Loom Knit Baby Sweater swatch for needle knitters

While this is a loom knit pattern, it is very simple to work on needles as well. Get the Loom Knit Baby Sweater pattern from Lion Brand to see the diagrams

NEEDLES: US 8 (5mm) needles
Knitters Pride Dreamz Interchangeable used in sample.

GAUGE: 4.5 sts and 9 rows in 1”

Back 45 (47, 50, 54)
Fronts 23 (24, 25, 27)
Sleeves 32( 34, 36, 41)

Remember that on needles you need to knit every row for garter stitch. That is the only stitch used in this pattern.

Hi, Derick! This is a tutorial I did for Lion Brand Yarn using their pattern. I have some basic measurement charts to help you figure out sizing for adults. From there you'd just have to adjust the dimensions of the pattern to the measurements you need. I know it's not much help, but scaling a baby sweater up to adult sizes is tricky because of they have very different proportions!
