This baby jumper is a mash-up of two existing crochet patterns, and while I can’t take credit for either, I’ll walk you through how I combined them, along with some small tweaks I made along the way. The inspiration came from the arrival of my friend’s beautiful baby girl, M. I needed something creative and compact—a project I could tackle during nap times and on my daily commute.
If you’ve been following along, you’ll know my go-to baby jumper is the Sweet Everly B Plain Jayne Sweater. I love the breathable, flexible fabric it produces—perfect for little ones. This formed the base pattern for my hybrid jumper. I used the 6–12 month size, but as long as you have at least 21 stitches across the chest by row 7 (or row 9 for this size), you’re good to go.
The next inspiration was the Daisy Farm Crafts Crochet Gingham Heart Baby Sweater which I will be making at some point in the future.
The second inspiration came from the beautiful heart motif in the Daisy Farm Crafts Crochet Gingham Heart Baby Sweater—which I fully intend to make in its entirety someday! I adapted their heart graph into the Plain Jayne sweater, using a solid-color overlay. Because the extended single crochet (ESC) stitch from the Plain Jayne sweater lengthens the shape, I reduced a few motif rows to maintain a clean, rounded, heart silhouette.
The Yarn I used
This was a stash-busting project, getting to use some yarn I had purchased years ago, waiting for the right project to come along. Unfortunately, one yarn had long lost its label. Here’s my best guess:
- Main Colour: ~2 balls of Mondial Cotton Soft Bio in a purple variegated color.
- Contrast Colour: Likely Lion Brand Cotton Bamboo Linen in white, or a similar weight and feel. (This is the unknown one). Any contrasting colour from the Cotton Soft Bio range would also work beautifully.
Materials Needed (6-12 month size)
Check the yarn needs for your base jumper size!
- 2 x 50g balls of main colour yarn
- 1 x 50g ball of contrast yarn
- 3.25 mm crochet hook
- 6 x stitch markers
- Heart graph gingham – get it from Daisy Farm Crafts
Skill level: Intermediate
You’ll need to be comfortable with colour changes, reading a graph chart, counting stitches, and modifying stitch placement.
How to Combine
I have written the exact steps I followed for the 6-12 month size and then added suggestions for what I would do if making a smaller/larger size.
- Choose Colour Pattern:
I made the cuffs and hem in the contrasting colour, which means you’ll need to start the ribbed neckline in that contrast and then switch to the main colour at Body Round 1. - Make the Sweater Yoke:
Follow the Plain Jayne pattern up to the end of:- Row 9 for 6–12 months
- Row 7/8 for smaller sizes
- Row 10/11 for larger sizes
This ensures the heart sits just above the armhole for that classic chest-centered look.
- Position the Heart Motif:
The motif is 21 stitches wide. Since the front panel has an even stitch count, the heart won’t sit perfectly centered—but don’t worry, it’s not noticeable when worn.
To calculate placement:- Subtract 21 from your total front panel stitch count (e.g. 38 – 21 = 17)
- Divide by 2 → (e.g. 17 ÷ 2 = 8.5)
- Mark either the 8th or 9th stitch as your motif start point, depending on your centering preference.
- Work the First Row of Heart:
Continue the next row as per the base pattern until you hit the stitch marker—this is where the motif begins. Follow the motif from top down.
Tip: Ensure colour changes are made with tails to the wrong side of your work. I carried the yarn behind the work and crocheted over it, keeping things neat. You can find a video tutorial here and a written version here. - Continue with the Motif:
Work in rounds, continuing both the main sweater pattern and the heart graph until the motif is complete. Carry yarn back along the previous row between rounds—watch how around the 2:30 mark in this video. - Ribbed Band and Finishing Touches:
For the sleeve cuffs and body hem, switch back to your contrasting colour for a pop of polish. Weave in ends and block as needed.
And thats it. You’ve got yourself a sweet, semi-customised baby jumper! Scroll down for printable PDF and tutorial videos.
