I finally have some time to get back into building and was starting the FW-42 build for FF 2018 - Ohio. I really hate trying to hold the plans and tape them together. I recently purchased magnetic pushpins from Amazon. Those and a 24 inch steel rule make taping plans much easier. Start with holding down one tile with a few magnetic pushpins. Then cut a couple tabs in the second tile to aid in alignment. Fold the tabs back a little and align the second tile. Hold it in place with more magnetic pushpins and tape. This way even little interruptions don't affect the alignment.
