Summary Sometime you need change place of wall shelf (bookshelf) or remove and place it to another place (especially in child room). After that remain ugly opening and situation lasting to redecorate... (and after that suddenly need to change back... :) ) So for this purpose i made this dowel cap. Here are two types - one with square cap and smaller with round cap. Cutting the tails edge is esay to adjust for opening size. Enjoy!
