Eersida 30 Pcs Building Blocks Party Favors Hanging Swirl Decoration Set with Single Double Hanging Swirl for Building Block Theme Birthday Ceiling Decor

A cheerful, low-lift way to fill a room with color—if you plan ahead

I tested the Eersida block swirls for a building-block–themed birthday and came away impressed by how much color and motion they add for relatively little money. They’re bright, lightweight, and easy to hang in a variety of spaces. The trade-off: they arrive as components and require a fair bit of assembly. If you carve out time to put them together, they reward you with a cohesive look that reads instantly “block party” without being cluttered.

What’s in the set

The kit includes 30 hanging swirls total: a mix of single swirls with a block cutout and double swirls that add some extra movement. Each piece consists of:
- A foil spiral (precut and coiled flat)
- A printed cardstock “block” element in bold primary colors
- A small connector (clear thread or plastic link) to attach the block to the swirl
- A plastic C-hook for the top

You also get enough components to assemble all 30, but you’ll still need a way to secure them to your ceiling or fixtures—think painter’s tape, thumbtacks, or removable adhesive hooks. The included plastic hooks clip to the swirl; they don’t stick to paint on their own.

Assembly and setup

Expect to assemble these. Out of the package, you’re attaching the block cutouts to the foil swirls and clipping on the top hooks. There were no instructions in my box, but the process is straightforward once you do one or two:
1. Uncoil the foil swirl gently; it springs open into a helix.
2. Thread or clip the clear connector through the punched point on the block cutout.
3. Attach the other end of the connector to the small loop at the end of the foil swirl.
4. Clip the plastic C-hook to the top hole of the swirl.

Assembly is simple, but it’s repetitive. Doing all 30 myself took a little over an hour at an unhurried pace. If you’re tight on time, pre-assemble the night before, or divide and conquer with another adult. I also recommend keeping the finished swirls in gallon zip bags by length (singles together, doubles together) to prevent tangling.

Design and build quality

The design is clean and unmistakable: classic block studs printed in vivid reds, blues, yellows, greens, and oranges. The palette reads playful and gender-neutral, which helped me tie together mixed decorations (balloons, a cake topper, tableware) without obsessing over exact color matches.

Print quality on the cardstock is crisp with saturated colors; the foil swirls are a standard party-weight thickness. I tugged on the connectors and edges a few times while testing and didn’t have any tearing or fraying. They survived a two-hour party with kids running under them and a ceiling fan on low. If you avoid creasing the foil and store them flat, they’re reusable. I packed them back into their sleeves and they looked fine for round two a week later.

One note on scale: the cardstock block pieces are modest in size. They read well from across the room because of the bright colors, but they aren’t oversized. If you’re decorating a large hall, plan to group swirls or supplement with a backdrop or balloon garland for focal areas.

Coverage and layout

With 30 pieces, you can cover a small party room, kitchen/dining area, or a section of a community room. The double swirls add nice dimension when layered with single swirls. Here’s what worked for me:
- Cluster 5–7 pieces above the cake or gift table to create a focal point.
- Stagger lengths down a hallway to lead guests to the party area.
- Mix doubles and singles over open spaces to avoid a “flat” ceiling line.
- Leave 12–18 inches between pieces for a full look without overcrowding.

If you’re worried about uniformity, measure and mark hanging points with low-tack tape first. I usually use Command mini hooks for textured ceilings and painter’s tape rolled into loops for smooth ceilings. Thumbtacks are fine if you’re not concerned about tiny holes.

Tips to make setup smoother

• Pre-assemble in batches: put together 10, hang them, then move to the next batch. It keeps the counter clear and reduces tangles.
• Add extension where needed: if your ceiling is high, tie a short length of fishing line to the top hook to lower the swirl without adding visual clutter.
• Keep the AC/fan on low: just enough airflow to keep the swirls moving looks lively; too much and they can flip onto themselves.
• Mix heights intentionally: even a few inches of variance keeps the display dynamic.
• Save the sleeves: slide the finished swirls back into the packaging to keep them from tangling between uses.

Durability and reusability

For lightweight party decor, these hold up well. The foil doesn’t kink easily if you handle it gently, and the cardstock is thick enough to resist curling during the event. The connection points are the weak link on many swirl sets; here, the small connectors stayed put for me. After two uses, a couple of connectors loosened slightly but were easy to reattach.

Storage matters. Coil the swirls back around the cardstock loosely; don’t fold. If a connector goes missing, a small length of clear thread or even a paper clip can stand in during a pinch.

Where they shine—and where they don’t

Strengths:
- Bright, cohesive theme that immediately reads “building blocks” without looking busy
- Generous quantity for small to medium spaces
- Lightweight and flexible for different ceiling types and venues
- Reusable if stored carefully

Limitations:
- Assembly takes time; plan at least an hour for the full set
- No adhesive or ceiling mounts included; you need your own tape/hooks
- The block cutouts are modest in size; supplement for large venues or photo backdrops

Who they’re for

If you’re planning a block-themed birthday, school celebration, or playroom refresh and want color, motion, and an easy thematic signal, the Eersida block swirls do the job well. They’re particularly good for home parties where you’re decorating one or two zones and can invest a little time the night before.

If you’re decorating a large rental space solo right before guests arrive, or you want decorations you can pull straight from the package and hang in minutes, the assembly requirement may be a sticking point. In that case, consider mixing a smaller batch of these with a ready-made banner or backdrop to balance effort and impact.

Value

Given the quantity and the overall finish, I consider these good value. You get enough pieces to make the room feel intentionally decorated, not just sprinkled. The ability to reuse them stretches the dollar further, assuming you pack them away carefully.

The bottom line

The Eersida block swirls are cheerful, reliable, and flexible party workhorses with one caveat: they demand a little of your time upfront. If you can spare that hour to assemble and have some tape or hooks on hand, they’ll give you a cohesive, colorful ceiling display that ties a block theme together instantly and holds up through the party.

Recommendation: I recommend these for most block-themed celebrations, especially home or classroom parties where you can prep in advance. They deliver strong visual impact for the cost, the materials feel sturdy enough for multiple uses, and the color palette plays nicely with other decorations. Just plan assembly time into your party prep and you’ll be happy with the result.
