Finding suitable storage for the pens which are popular at the moment can prove to be a tricky task. The storage which is purpose built is often not quite what you're after, and is often expensive too.
Gina from the Promarker Workshops blog has made her own storage, using an idea originally by Camilla. A cheap DVD unit is the starting point, plus some empty DVD cases. Storing promarkers like this is better for the pens, they should always be stored horizontally, not vertically. You can also adapt the size of the storage to suit the number of pens you have, maybe choosing a smaller DVD unit if you have yet to increase your pen collection.
Gina used a colour chart created by her friend Debbi, and on the promarker blog she is happy to email out copies, so I am sure that offer is still open. Click on the link on her blog for more details.
I think this storage looks great, and at £7.99 for the DVD rack, plus 14 empty DVD cases, it is hardly breaking the bank!
