Do you know how to do drafting of patterns? You would need to draft the patterns for 2 different size bow tie blocks, and then you could use the picture to help you figure out how many blocks of each size to make, and also use the picture as a guide to laying the bowtie blocks out. It really wouldn't be too hard, just some basic quilting math skills, lots of cutting and sewing.
Maybe make just a block or 2 in each size to get started and to make sure your math is correct, and then you could get busy making lots of bowties.
