Stamping is much more consistent and will save your hands a bit of pain. Also a decent idea is to split your 24 words into 3 groups of 8 (A = words 1-8, B = words 9-16, C = words 17-24). Make two copies of each set of 8 (ie 2 As, 2 Bs, 2 Cs). Then make three bolts, one contains a set of A + B, one is A + C, and a third is B + C. Hide them in different locations. That way if you lose one, or if someone finds it, they only have part of your phrase and not the entire thing. You (or a thief) would need any two of the three sets to recover/steal funds.
