I am planning on using deep litter method also which is why i grabbed up the free material. I bought my bag of shavings at a feed supply store and was suprised by the price. I'm hoping combining the two in the right proportion will work!
This was the same question i had! I bought a bag of course shavings for $6, then i found someone giving away 55gallon bags of wood working shavings for free! But once i saw them i was afraid to use them because they are much finer. I had the same thought that if i combined the two, it could work...
