I recommend getting a dry erase board or a cork board.

我推荐使用干擦板或软木板。

The goal was to affix a lit candle to a cork board with nothing but those items.

我们的目标是用这些东西把点燃的蜡烛固定在软木木板上。

When I first started to put the book together, I  used this cork board behind me, actually.

事实上，当我第一次开始整理这本书时，我使用了我身后的这块软木板。
