I think it is so fun being able to crochet items for various holidays.
This pattern is a fun crochet hat for St. Patrick’s Day. Wear this for photos or gatherings or while attending your local St. Patrick’s Day parade during the month of March.
Pattern Details
The only difficult part about this hat would be the color changes. You will also need to follow a graph in order to complete the brim of this crochet beanie.
There will be instructions to guide you on how to follow the graph properly.
There are 3 different sizes that this hat can be made in – Toddler, Child, Adult.

The toddler version is written so that it is a square shape. The other 2 sizes are a slouchy style hat.
If you prefer just a beanie style then you can easily crochet less repeats than the pattern states.
This pattern uses a worsted weight yarn. If you love patterns that use worsted weight #4 yarn then check out this roundup of over 50 free crochet patterns using that weight of yarn!

I hope you enjoy making this fun St. Patty’s Day hat for your whole family!

Instructions: Lucky Leprechaun Crochet Beanie
Toddler (Child, Adult)
BRIM
With A, ch 56 (62, 66), join to first ch.
Read the following instructions before following the brim graphs below for each size.
- Each stitch of the brim is a sc st.
- After round 1, each brim round will be worked in the blo (back loop only).
- Carry A up the seam when joining each round.
- To avoid carrying color C around the brim, create 2 small balls of yarn to use for the belt buckle.
- The red arrows in the belt buckle indicate which stitches to use ball 1 for of color C and the blue arrows indicate which stitches to use ball 2 for.
- Fasten off B & C after the last brim round.
- The stitch counts are below each graph. There will not be a box represented for each stitch on the sides of the buckle so check your stitch counts. The stitch counts show the range count on each side of the buckle.

Fasten off and weave in ends.
For each corner, cut 22 8-inch strands of a variety of colors. Fold the strands in half and pull through a corner using a crochet hook and attach like fringe. Leave long or cut shorter.
