Ideas Only ---This is a project using Transfers/Decals---NOT FOR SALE
I used my own design decal/transfer on my card container.
First removed it in tepid water from backing. Place in position on the container, gently rub with a dry cloth and rub out any bubbles in transfer. Leave to dry and then when dry brush a coat/coats of varnish over it.
This will not need washing so not so many coats of varnish are required ;-)
***CHEATS WAY TO DO IT*** +put transfers/decals into place. +leave to dry and then brush over with clear varnish, three/four coats required. DA-DA-DAR !! (check every year, wipe over to remove surface dust and decide if a new coat of varnish is required)
For a selection of transfer/decals please take a look at Transfer/decal section in Rustydusty shop....Thank you and happy projecting !!
