since most of the decoration and furniture in my kitchen is white i wanted all of my vases to look like that, too. unfortunately i didn't have so many white vases but on several blogs i have read about the idea to use pickle glasses of different shapes and colouring them white so that one can use them as small vases afterwards. i liked this idea very much and thus i gathered loads and loads of them, bought varnishing spray in white and started my new DIY project!
what is most important is that you're working outside (if possible) and that you've got enough support surface because the spray will have a huge diameter. thus i have chosen some of my old moving boxes. with a distance of approx. you should stick to a distance of 15-30cm between they spray and the glass you want to colour. in a few hours the glass should be dry. but precautionary i have waited one day or 24h until i put them back inside.
another time you're getting best results for less work. i love the look of the new vases. the different shapes add a fun and also sophisticated twist on the table.
