I also have the metal drawers. I always keep my white and cream seperate, then mirri, dufex and patterned foil. I don't use coloured card very much, that's why I have tons of it. I bought a deep A4 box on special a couple of weeks ago from Hobbycraft, and I can just manage to get the lid on.
oh!!! went to Staples yesterday to but a mouse mat for my Grandson, and they have sets of 2 A4 drawers (attached) for £4.99. So my £5 mouse mat ended up costing £25!!!I have all my papers separate, foils, vellums, patterned and plain. I can't be doing with having to search for everything. I had a million off cuts, that I got so fed up with, they all went into the bin!
Those drawers are expensive, but are guaranteed for life, and they're brilliant. HTH, luv Jacqui xx
