Rectangular Granny Square Blanket

DO THE MATH

Brenda has a simple formula for determining the length of the foundation chain for the rectangular granny square blanket.

Intended Finished Length of Blanket – Intended Width of Blanket = Length of starting chain needed

For example, if you wanted to make a very large blanket that’s 10 feet tall by 6 feet wide, you’ll need a starting chain of 4 feet (because 10 – 6 = 4). Depending on that type of granny square you’re working you’ll need to make sure you have the correct multiple of chains in the foundation chain.

GRANNY SQUARE WITH CHAIN SPACES

For a rectangular granny square blanket with chain spaces, Brenda uses a slightly modified version of the traditional granny rectangle by starting the first round without groups of double crochets. This allows the center to look more uniform and symmetrical. For this rectangular blanket, use the equation above to determine the length of the foundation chain. Then chain a multiple of 4 until you reach that length. Six extra chains are then added, for a multiple of 4 plus 6 chains total. Brenda starts with 30 chains for the sample shown in the video. Following the pattern, she works the modified rectangular granny square with chain spaces.

GRANNY SQUARE WITHOUT CHAIN SPACES

Like the version with chain spaces, Brenda starts this rectangular granny square slightly modified from the traditional way. She once again uses the equation to determine the length of the foundation chain that is needed. She chains a multiple of 3 plus 4 in order in this version of the blanket. In her sample, she works 19 chains. She follows the instructions for the modified granny squares without chains to create the rectangular granny square.
