Materials: SUMMERA pull out keyboard

Question: This is not an actual hack but an idea that I have of converting the Summera pull out keyboard to a pull out ironing board by covering the board with batting and linen. This will be drilled under the Linnmon desk because this is what I was planning to use as a sewing table. I would be grateful if anyone can give their input or ideas on this. Thanks!
