Small Square Blanket, Lapghan, Afghan, or Twin Bed Size Blanket Large diamonds cover this blanket. Alternating diamonds have smaller diamonds within them. Worked with knit and purl stitches only, Grand Prairie is a good Beginner-with-a-bit-of-experience pattern. It looks just as good on the wrong side as it does on the right. The pattern calls for worsted weight yarn. Instructions are given for four sizes. The lapghan is especially useful for a larger person who uses a wheelchair. The instructions are written out and chartered. This would be a good project to learn to knit from a chart. It is all one piece, so whenever you have woven on the last tail, you’re done! No seams!
