Discover the perfect foundation for your card making projects with our versatile cardboard and cardstock paper selection. Our 300GSM double-sided glitter cardstock offers premium quality with vibrant colors like royal blue, emerald green, and rose gold - ideal for creating stunning invitations and greeting cards. The thick, durable material prevents ink bleed-through while the embedded glitter adds elegant shimmer without messy fallout. These professional-grade sheets measure 8.5x11 inches, the standard size for most card making projects and die-cut machines. Corrugated cardboard sheets provide excellent structure for DIY card bases, scrapbooking, and 3D craft projects. The 2mm thickness offers optimal sturdiness while remaining easy to cut, fold, and decorate. These versatile sheets serve dual purposes - create dimensional card elements or use them as protective backing for shipping finished creations. Our cardboard maintains its shape under layers of embellishments, glue, and paint. For seasonal celebrations, our themed craft kits like the Mother's Day Flowers Card Kit include pre-cut foam shapes and coordinated components. These all-in-one solutions simplify card making while delivering professional-looking results - perfect for classroom projects, party activities, or personal crafting. The kits contain everything needed to assemble beautiful handmade cards quickly and efficiently. Explore creative possibilities beyond traditional cards with unique supplies like cardboard shirt forms. These innovative bases can be transformed into fabric-covered greeting cards or dimensional art pieces. Whether you're creating simple thank-you notes or elaborate wedding invitations, our cardboard craft supplies provide the perfect foundation for your imagination.
