This crochet cardigan free pattern is SO much more versatile than just a lightweight cardigan for summer.
It’s a lightweight lace cardigan, but it’s fantastic for fall, spring, even winter if you live far enough south lol.
The pattern is a super simple two panel construction, but it’s assembled in left and right halves vs front and back. My first long sleeve design with this construction!

While it is technically a crochet pattern for a sweater, albeit a light one, it’s so light and lacy you could just as easily wear it to the beach over your bikini. In fact, I LOVE that idea.
Hence the title “lightweight cardigan for summer”. It can go pretty far in the other direction, but I think it’ll shine the most in the spring, summer and fall.
Of course if you’re looking for a crochet pattern for a sweater proper, I’ve got you covered there as well, but let’s enjoy some sunshine and light, cute sweaters while we can, shall we?

This lightweight crochet cardigan free pattern includes US women’s sizes XS-XXL. It’s meant to wear a little oversized and relaxed but you can adjust for your preferred fit.
I used Holst Garn Titicaca thin alpaca yarn in a #0 lace weight, but I doubled it to equal a #1 fingering weight. First time making a pattern that way as well!
I do love this yarn but feel free to use a fingering weight to start, just check your gauge before you start, regardless of the yarn you choose.

Joining Your Lace Cardigan Together
Sew The Center Back Seam
We will sew the center back seam first. Laying your panels with the right side facing down, we’ll sew on the wrong side. Lay the first row of each panel facing each other, cut about 40-50″ of a new strand of yarn with double strands. Using method of choice, sk 30(30, 30, 30, 30, 30) st, start sewing next 55(55, 60, 60, 65, 65) st of the center back of each panel together, weave the ends. Check picture below

Sew The Sleeve and The Lace Cardigan Side Seams
Fold your cardigan in half at the shoulder with the right side facing each other, we’ll sew on the wrong side, using the tails that we left earlier for sewing. Using method of choice, start sewing at the sleeve side seam until you reach the armpit corner. Then continue sewing the cardigan side seam down to the bottom then weave the ends. Sew the same on the other side. Check picture below
