About JellyCalc
JellyCalc is a planning and design app for jelly-roll rug makers. It combines accurate fabric calculations with JellyCalc Designer, an interactive visual designer, so you can plan and design your rug with confidence. JellyCalc Calculator Calculate fabric and strip consumption for your jelly-roll rug based on size and layout. Adjust dimensions and instantly see how your requirements change. JellyCalc Designer Design your rug visually using colors from a palette, or real fabric strips from existing jelly-roll precuts. Resize your rug and watch the design update in real time — create a mockup that closely matches how your finished rug will look once sewn. Whether you want precise calculations, a visual preview, or both — JellyCalc helps you plan smarter and sew with confidence.
