Glow-in-the-Dark Yarn vs Lion Brand DIY Glow: Honest Side-by-Side Comparison (2026)

If you've searched for "glow-in-the-dark yarn" lately, you've probably seen two names come up most often: Lion Brand DIY Glow (the craft store staple) and bulingbuling (the online specialty maker). Both produce yarn that glows in the dark, but they take very different approaches to colors, pricing, and texture.

This comparison is based on publicly available product specifications from both brands. We'll tell you where each excels — and where each falls short — so you can pick the right yarn for your project without guesswork.

At a Glance: Side-by-Side Specs

Head-to-Head Breakdown

1. Color Selection: BBY wins decisively

This is the biggest difference between the two brands. bulingbuling offers 41 colors of glow polyester yarn — including Pumpkin Orange, Black, Purple, Red, Green, and White.

Lion Brand's original DIY Glow comes in one color (an off-white that glows yellow-green). Their Twist line adds 6 twisted color combinations. Their Cozy line adds 6 solids.

The reality: If your project needs to BE a specific color during the day while also glowing at night — for example, an orange pumpkin, a black spider, or a green monster — Lion Brand gives you very limited options. BBY has all those colors ready to ship.

Winner: bulingbuling — 41 colors vs 1–6 colors is not close.

2. Price: BBY is 43–53% cheaper per skein

At $3.99 per 50g skein, bulingbuling's glow polyester yarn costs roughly half of Lion Brand's $6.99–8.50 per comparable skein.

Per-gram breakdown:

• BBY: $0.08/g
• Lion Brand DIY Glow Original: ~$0.14/g
• Lion Brand DIY Glow Twist: ~$0.09–0.13/g

For a large project like a glowing throw blanket (which might use 10+ skeins), this difference adds up fast — BBY would cost ~$40 vs Lion Brand's ~$70+.

Winner: bulingbuling — significantly lower price per skein.

3. Texture & Yarn Weight: Different tools for different projects

This is where Lion Brand has a clear product difference worth noting.

Lion Brand DIY Glow is Worsted weight (CYC #4) — thicker and heavier. The yarn has a slightly stiff, synthetic texture that holds its shape well for structured projects. The DIY Glow Cozy variant is softer, and the DIY Glow Twist adds a two-tone twisted effect.

bulingbuling glow polyester is DK weight (CYC #3) — slightly thinner than Lion Brand's original. It's smooth and works up cleanly with a 3.5mm hook (US G6). The chenille version (also available, $4.99) is velvety soft — significantly softer than Lion Brand's standard glow yarn.

In short: If you want worsted weight for a project that calls for bulky stitches, Lion Brand is better suited. If you prefer DK weight for finer detail or want a chenille option for plush projects, BBY offers that.

Winner: Tie — depends on what weight your pattern calls for.

4. Brand Recognition: Lion Brand has the edge

Lion Brand has been in the yarn business since 1878. It's sold in every major craft store (Michaels, Joann, Hobby Lobby) and has widespread brand recognition among crocheters and knitters.

bulingbuling is a smaller specialty brand, operating direct-to-consumer since 2003. It's not available in physical stores.

What this means for you: If being able to buy yarn in person matters — or if you need it the same day — Lion Brand's retail distribution is a real advantage. If you're planning ahead (which most Halloween projects require), BBY's 2–4 day shipping and free shipping over $20 compensate well.

Winner: Lion Brand — easier to find in stores.

5. Glow Performance: Both use strontium aluminate

Both brands use strontium aluminate-based phosphorescent pigment, which is the modern standard for glow-in-the-dark products (far superior to older zinc sulfide formulas).

• BBY claims: 6–8 hours of glow after full charge
• Lion Brand claims: "glows for hours" (no specific number)
• Third-party tests: Independent reviews consistently show both brands glow for 30–60 minutes at visible brightness, with residual glow fading over 4–6 hours. Both require re-charging under light for continued effect.

Honest note: The claimed "6–8 hours" for both brands refers to the total duration the pigment remains technically active — not 6–8 hours of bright visible glow. The brightest glow lasts about the first hour, then gradually fades. This is normal physics for strontium aluminate phosphors and applies equally to both brands.

Winner: Tie — comparable glow technology.

6. Safety & Certifications

bulingbuling's glow yarn is OEKO-TEX® Standard 100 certified — meaning it's been independently tested for harmful substances and is safe for all ages, including children's toys and baby items.

Lion Brand's DIY Glow line does not carry OEKO-TEX certification (it meets basic US consumer safety standards).

For baby or children's Halloween projects, this may be a factor worth considering.

Winner: bulingbuling — third-party certified safe.

Which Should You Choose?

The honest bottom line

If color variety and price are your priorities — and they usually are for Halloween projects where you need specific shades like orange, black, and purple — bulingbuling offers better value and more creative freedom. The $3.99/skein price with 41 colors is hard to beat.

If you're a die-hard Lion Brand fan, need worsted weight, or want the convenience of buying in a physical craft store — Lion Brand DIY Glow is a perfectly good product. Just be aware that the color options are limited and the per-skein cost is higher.
