Soo - a while ago I showed the last photo and said that I have something in mind - studding idea. And it took a while to get the studs, but finally today I did it.
And honestly, this was literally a bloody DIY, because I stabbed and cut my fingers countless times - Im starting to think that this wasnt very smart idea to put spikes on boots, because I might get some other injuries or stab some other people or pets when wearing these boots - these spikes are really sharp. But for now I will leave them in boots.
Plus I think I need more shorter studs to fill the gaps, because I had only limited amount of spikes, and it would look better with more spikes.
Have a wonderful day!
