What are the most popular soft substrates to sublimate currently?

The same thing I said about hard substrates applies here in terms of popularity. With that said, here are some trends for soft substrates:

• T-shirts – still at the top of the list.
• Floormats – there has been a huge upsurge in floor mat sublimation. It’s a low-cost product with high margin potential.
• Flags – lots of flag products available, from car flags to garden flags and house flags.
• Socks – they offer many opportunities, from uniforms to souvenirs.
• Baby products – onesies, burp cloths, and more.
