A tool designed to estimate the number of granny squares required for a blanket project, typically taking into account desired blanket dimensions and individual square size. For example, a user might input a desired blanket width of 50 inches and a length of 70 inches, along with a granny square size of 4 inches. The tool would then calculate the approximate number of squares needed.
Such tools simplify project planning by removing the guesswork involved in determining yarn quantities and construction time. This is particularly valuable for complex projects or for crafters who prefer a precise approach. Historically, crafters relied on manual calculations and experience. Digital tools provide a faster, more accessible, and often more accurate method. This aids both experienced crocheters and beginners, making the craft more approachable and efficient.
