We are deeply sorry for the problems you have encountered using Woodblocx.
The rough quality timber is made that way to keep it looking as authentic as possible to enhance the final design. Depending on the design, or by request we sand down sections of the Woodblocx. This is very common with benches and seating designs.
We are sorry you had trouble with the instructions you received. The basic instructions included are there to simplify the building process of how to connect the blocks and insert the dowels. We use these instructions on all of our designs regardless of the shape or complexity of the build. The colour key along with the layer by layer instructions should match all designs that we process as they are all generated from the same CAD design.
Sorry again for any confusion this process may have created.
Please don't hesitate to get in touch if you experience any further problems.
Hope your design turned out well in the end.
