Here’s an insurance policy for your corners! This way you’ll never have issues with the ends not meeting up together!
If you decide to do this, you just need to make sure that you keep your corners having only three wefts at a maximum! So if you fold over, you now have the density of two and have the option to place one more weft meeting on the end bead. After that, you’ll want to set back any wefts you choose to layer off those first few beads you wrapped. Thanks for the inspo @joliefaulkner !!
