If you go fishing and get bottles, save the heck out of them! At least get 5 for the cloth maker but do your best to get more for other machines. Save all small rocks, rocks, and black rocks. Small lumber, lumber, and black lumber. Save a bit of each herb you find (at least 10-20 each) Keep them in your fridge for safe keeping. Save bee's for bee keeping in the beehives you'll make with honeycombs. When you open the mine, save all the items you get from it until you know that you are absolutely done needing them for town renovations or item making. Save all glass stone and all types of ore as well. Bottom line: hoard like....everything.

I'm literally in the same boat as you. Well at least this gives me time to obtain more gold ore for my future hubbies home.
