Free Loom Knit Envelope Hat Pattern

Free Loom Knit Envelope Hat Pattern

Inside: Free loom knit Envelope Hat pattern in 6 sizes from Baby to Adult Large. Includes written instructions and tutorial videos.

When I published my How to Loom Knit an Envelope Hat instructions, I knew I needed to create a pattern too.

Instructions are great when you’re experienced, but if you’re relatively new to loom knitting, a pattern can help take the guesswork out of it for you.

Since I made so many samples of envelope hats with a variety of loom gauges and yarns I needed to pick just one. I decided to make the loom knit Envelope Hat pattern using medium (#4) weight yarn and a 3/8″ small gauge (SG) knitting loom. Both of these are easy to find and you may have them already.

The Basic Envelope Hat creates a unique design with a flat top with square corners that you can embellish with pom poms or tassels.  The hat is loom knit from the top down and uses the Kitchener cast on to create the seamless top.

This pattern includes written instructions for 6 sizes from baby to adult large and fully captioned tutorial videos teaching the Kitchener cast on.

SIZES Baby (Toddler, Child, Small, Medium, Large)

Circumference 12.75 (15.5, 17.5, 19.5, 21.25, 23.25) inches by 6.75 (8, 8.5, 9, 9.5, 10)  inches in height* [32.5 (39.5, 44.5, 49.5, 54, 59) cm by 17 (19, 20.5, 21.5, 23, 24, 25.5) cm]
*Height includes flat brim only.  Total height will be 1.25-2” more for a folded brim.


This hat is worked from the top down to the brim using the Kitchener cast on. If you are new to this cast on I have included the video for you below. You may also want to refer to my Loom Knit Kitchener Cast on blog post.

Since the brim is worked last, knit your hat to your desired length minus 1.25-2 inches for the brim.  Be sure to bind off loosely.

Hat is worked in the round.  For right handed knitters work from right to left (clockwise). Work in the opposite direction for left handed knitters (counter clockwise).  

All knit stitches in the main body of the hat are Uwrap knit.  Be sure to work loosely to achieve correct gauge.  You may use Ewrap knits, but your hat will be a bit larger than the listed size.  Ewrap knit stitches are recommended for the brim.
