Are these suncatchers safe around children?

Yes, with care. The materials are non-toxic when made from food-safe ingredients like agar or food-grade gelatin, glycerin, and food coloring. However, the process uses heat. Always supervise children and handle hot liquids yourself. Once fully cured, the sheets are safe to hold, but small parts like threads or hooks may be a choking hazard for very young children.

How long do they last?

With gentle care, a suncatcher can keep its shape for months to years. Exposure to direct, intense sun and heat will change them faster. Store flat, avoid high heat, and give pieces time to fully cure for best longevity.

Can I make them waterproof?

The sheets resist light moisture but are not fully waterproof in the long term. Avoid soaking them. If you need more water resistance, a light coat of a clear, eco-friendly sealant designed for crafts can help, but test a small patch first. Many makers prefer to keep them naturally breathable.

What if my sheet cracks when I lift it?

Cracks usually mean the sheet dried too fast or did not have enough glycerin. A small amount of warm glycerin applied to the crack and smoothed can soften the edge. For future batches, slightly increase the glycerin or let the sheet cool more slowly.

Can I recycle the scraps?

Small scraps can be composted if you used plant-based ingredients like agar or cornstarch. If you used gelatin, check your local composting rules. Otherwise, collect scraps for small repairs or for experiments where you remix the material into new pieces.
