All parts come in bags with alphabetical labels and are numbered in the instruction manual. Round up the parts you need for your next item, identify each piece by matching dimensions with the instruction. Then organise them on white paper (or dinner plate / tupperware).
Follow the instructions step by step using only the pieces assigned for the item you are working on, take your time. Sometimes it's better to let the glue dry on an item while you move to the next one.
Check out the pages here for information to wire lights and Tips label to get help with some of trickier items (like palm trees)
In no time at all, you will have many items completed and your miniature will appear. Enjoy and relax!
