20 Pcs Macaron Heart Shaped Buttons for Sewing — Pastel Colors, 3 Sizes 12.5mm, 15mm, 18mm

These heart shaped buttons bring a soft, pastel-sweet touch to any sewing project — whether you’re finishing a hand-knit baby cardigan, embellishing a child’s dress, or adding decorative detail to an adult knitwear piece. Made in the macaron color palette that’s become a staple in cottagecore and handmade baby fashion, each button is a flat 2-hole sew-on style in a rounded, distinctly heart-shaped silhouette with a raised heart-outline rim.

Available in 9 individual shades — Blue, Purple, Mint Green, Baby Pink, Rose Red, Red, White, Off White, and Butter Yellow — plus a mixed pack, these decorative buttons for sewing cover the full spectrum of soft pastel projects without requiring you to search across multiple listings.

What It Does / Who It’s For

These heart shaped buttons for sewing are the go-to for anyone working on garments that need a fastening with personality. The 12.5 mm size was specifically selected for newborn and infant clothing — the standard size range for baby cardigans, rompers, and sleep sacks where a small button makes a big visual statement. The 15 mm works beautifully on toddler and children’s clothing. At 18 mm, these large heart buttons are sized for adult garments: cardigans, shawls, and handknit coats.

Beyond garments, crafters use them as heart shaped buttons for crafts — scrapbooking, card making, and handmade gift embellishments where a soft pastel heart adds instant charm.

Why You’ll Love Them

• Nine coordinating shades in one palette: the macaron color range was designed to go together, so mixed-pack orders always look curated, not random
• Three sizes in one listing: from newborn through adult, without sourcing from multiple shops
• Semi-matte finish: sits quietly on garments without reflecting light or competing with the stitchwork
• Standard 2-hole construction: compatible with hand-stitching and any standard button-attachment method

How These Compare

Most heart button listings carry one or two sizes, typically focused on either baby or adult garments — not both. These large heart shaped buttons and their smaller 12.5 mm counterparts ship from the same listing in the same 9-color palette, so you match your size to your project without compromising on color. The macaron palette is also distinct from primary-color or jewel-tone alternatives: the low-saturation pastels are a deliberate aesthetic choice popular in handmade baby fashion, cottage core knitting, and Valentine’s Day gift projects.

Sizing, Materials & Care

• 12.5 mm — newborn and infant garments: rompers, sleep sacks, baby cardigans
• 15 mm — toddler to children’s garments: dresses, jackets, kids’ cardigans
• 18 mm — adult garments: cardigans, shawls, adult knitwear
• Material: Plastic (not acrylic, not wood, not metal)
• Care: Machine washable; holds color through standard cycles; avoid high-heat drying on delicate handknits

FAQ

Are these safe for infant clothing?
The buttons are sewn on through 2 holes and hold securely when properly attached. For garments intended for infants under 12 months, sew buttons firmly using a button shank or reinforced thread — this applies to all sew-on buttons regardless of material.

What’s the difference between the 12.5 mm and 15 mm sizes?
The 12.5 mm is the standard “baby button” size for newborn-to-6-month garments. The 15 mm suits 6-month-and-up baby and toddler clothing where slightly larger buttons suit the garment proportions better.
