Why You’ll Love This Cardigan
This cardigan combines everything people love about handmade Crochet clothing — softness, warmth, comfort, and effortless style. The oversized raglan fit makes it easy to layer, while the curved edging and folded collar give it a polished boutique-style finish.
Because it is worked from the top down, you can try it on as you go and adjust the fit easily. The chunky 10mm hook also means this is a satisfying project that works up surprisingly quickly despite its cosy oversized feel.

Construction and Stitch Detail
The cardigan uses simple Half Double Crochet and Single Crochet stitches throughout, making it approachable even if you are newer to Crochet garments. Half Double Crochet creates a soft dense fabric with gentle stretch, while Single Crochet helps add structure around the edging and shaping.
The raglan shaping is created through easy increases, giving the cardigan a comfortable fit around the shoulders without bulky seams. Because the construction is repetitive and relaxing, this pattern is perfect if you want your first wearable Crochet project without complicated shaping.
Yarn and Feel
Debbie Bliss Cashmerino gives this cardigan a soft luxurious feel while still keeping enough structure for the oversized shape. The merino and cashmere blend creates warmth without heaviness, making this the kind of cardigan you will keep reaching for throughout colder months.

Hooks, Tools and Scissors
These are the tools I would recommend for this project size and yarn weight.
Common Mistakes to Avoid
- Using stiff chunky yarns that remove the cardigan drape
- Skipping gauge checks when substituting yarn
- Over-tightening the neckline ribbing
- Adding too much sleeve length before checking fit
- Hanging the finished cardigan instead of folding it
Stitches Used in This Crochet Cardigan
This Merino Raglan Cardigan uses simple beginner-friendly Crochet stitches, but the finished fabric still looks beautifully soft, structured and wearable. The main stitches are used to create a warm, flexible cardigan fabric with enough stretch for comfort and enough structure to hold the raglan shape.
Single Crochet / Double Crochet
US term: Single Crochet (sc)
UK term: Double Crochet (dc)
This stitch creates a neat, firm fabric that helps the cardigan keep its shape. It is especially useful around edges, button areas and places where you want a little more structure. In this pattern, it helps balance the softness of the chunky yarn so the finished cardigan does not feel too loose or floppy.
How to work it: insert your hook into the next stitch, yarn over, pull up a loop, yarn over again and pull through both loops on your hook.
Half Double Crochet / Half Treble Crochet
US term: Half Double Crochet (hdc)
UK term: Half Treble Crochet (htr)
This is the main stitch that gives the cardigan its soft, warm and slightly stretchy feel. It is taller than single crochet but not as open as double crochet, which makes it ideal for Crochet clothing. It gives the cardigan warmth without making the fabric too stiff.
How to work it: yarn over, insert your hook into the next stitch, yarn over and pull up a loop, yarn over again and pull through all three loops on your hook.
Using Different Yarn Fibres and Weights
This cardigan was designed with a soft merino-style chunky yarn and a 10mm hook, which gives the finished garment its warm, drapey and slightly luxurious feel. You can use other yarns, but the fibre and weight you choose will affect the finished size, stretch, warmth and overall look of the cardigan.
Merino and Wool Blends
Merino, wool and wool-blend yarns are ideal for this pattern because they give warmth, bounce and a beautiful natural stretch. They help the raglan shaping sit nicely on the shoulders and make the cardigan feel cosy without looking bulky. Wool blends may relax slightly after blocking, so always check gauge before starting.
Acrylic and Easy-Care Yarns
Acrylic chunky yarn can work well if you want a more budget-friendly or machine-washable cardigan. It may create a slightly lighter fabric with less natural stretch than wool, so check your measurements as you go. A soft premium acrylic or acrylic blend will usually give the best result for clothing.
Cotton and Cotton Blends
Cotton can make the cardigan feel heavier and less stretchy. It may create lovely stitch definition, but it will not have the same bounce as merino or wool. If you use cotton, choose a soft cotton blend rather than a firm dishcloth-style cotton, and be careful with length because cotton garments can grow with wear.
Changing Yarn Weight
If you use a thinner yarn, your cardigan may come out smaller unless you adjust your hook size, stitch count or rows. If you use a thicker yarn, the cardigan may become larger, heavier and bulkier, especially around the collar and sleeves. Always make a gauge swatch and compare it to the pattern gauge before committing to your size.
Tip: if your stitches are too tight, go up a hook size. If your fabric feels too loose or the cardigan is growing too large, go down a hook size. The goal is a fabric that feels soft and flexible but still has enough structure to hold the cardigan shape.

Hi!
In the coat body section, repeat row 2-3…there seems to be no row 3? Is it the second row 2?
Thanks so much for your help!
Hi, yes it is. I need to amend this. Thanks
Hi. Is the pattern us US of UK format. A size 10mm crochet hooks seems very big ??
Many thanks
Hi, it is written US terms.
You will use a 10mm hook as pattern is made with super chunky yarn.
Thanks

Hi there, it’s a long time since I crocheted! With the WS and RS is that just to remind me what side I am on or do I have to not turn the work to remain on the WS, I’m referring to the body section second and third row? Many thanks.
Hi, yes it’s a guide really to show you are on track. If there are markers in place etc to check you are working correct row.
Thanks
Emma
Hi there. I’m fairly new to crochet so forgive me if this is a simple answer haha. How do you work the (7, 8, 10, 11, 13, 14, 16, 17 hdc) in the body section?
Hi, this was a typing error. Thanks for pointing out to me. I have edited for you! Thanks Emma
Hi, so I already messed up and I am just finished row 5 so a frogging we will go. lol… but when moving the stitch marker do I place it in the start of the 2nd increase? I put it in the last of the increases and now I am super off center.
Hi, you will place the marker in the first stitch of the increase (directly above the marked stitch of previous row).
Hope this helps.
Thanks
Emma
The link to buy the pattern doesn’t work. Where can I buy it?
Hi, thanks for letting me know. It should be working ok now.
The pattern seems to be missing the instruction for Row 1 of the Sleeve Space.
Hi, thank you for letting me know 😊 I have amended this now x
I noticed it’s missing gauge and was wondering if you could possibly add the gauge I love this it’s adorable ❤️
