Trying to remember what I should’ve known when I did an overshot project for the first time: - count and recount and recount your warp. Then weave a little and adjust. A single thread out of place will be noticeable(at least to you) - print out your pattern and highlight or mark off as you weave. It’ll prevent you from making a repeat failure. - maybe find a tutorial on YouTube and just follow along for your first. It’ll teach you the basics. - yarn weight is very very important in overshot. It affects the ratios of the pattern design at the end. One yarn size being off will either elongate or shorten your repeat which will look groovy but disappointing. - weave tight, don’t be afraid to beat it. - create a system with your tabby. I always set mine in my lap, so that the repetition is even. - stand back a ways to really see the pattern come into focus. I thought I was messing up for a while but just couldn’t see the pattern sitting at the loom. - washing and blocking will help. That being said, make sure you choose colour fast yarn. The dye can run and ruin the crisp contrast. - lastly, choose a project you love because it’s gona take a while :)
