In reply to Hazelnuts: why bother making holds. On my home wall in the garage I have holds I bought and pieces of rock I pick up at diffrent crags from all over Europe that I have climbed on, just make sure they are flat or will lay flat without wobbleing on one side drill a hole through them an haypresto free holeds. When I put them on the wall I also write in perminant marker which crag the rock was from either above or below the rock. Now when ever I use my wall I get to remember all the places iv been. Works as good as any holds iv bought.
