If your measurements are all correct it will work. If they are slightly off then it can make things tricky.
Tip 1 make the triangle corners and borders from the log cabin before you fix any of it together. This will give you a good indication of placement.
If some of the blocks are off a bit then that didn't matter , just make sure all corners and borders on each side look the same.
