Crafters and small business owners, these blank canvas bags are perfect for your sublimation projects! You get 12 light yellow rectangular bags measuring 12.2x14.2 inches (31x36cm) - that's a dozen opportunities to create custom designs. Made from polyester material that's ideal for heat transfer, these bags are environmentally friendly and reusable, helping reduce disposable bag waste. The surface is pre-pressed for 3 seconds to ensure it's perfectly flat before sublimation, which means your designs come out crisp and clear every time. The recommended settings are 360°F for 60 seconds, but they also work great for heat transfer vinyl, screen printing, embroidery, or even fabric painting. The quality is solid with good stitching and durable material that holds up to regular use. Whether you're making personalized gifts, creating merchandise for your business, or doing craft projects with kids, these blank canvases give you endless creative possibilities. The light yellow color provides a nice neutral background that works with most designs. The company has over ten years of sublimation experience too, so they actually know what they're talking about when it comes to heat transfer techniques. Perfect for farmers markets, craft fairs, or just making unique gifts for friends and family!
