My office/craft room is a disaster area right now but it was adorable before the holidays!
I have a long desk (made out of a door we got at Home Depot. If you don't have the skills to make legs you can use two filing cabinets, one on either end. Super sturdy!
Half of my desk is for my computer and the other half is for crafting (under ideal conditions!)
I had two short book cases that used to sit under a window in our old apartment but in this apartment I lined them up next to each other and bought four super cheap and extra long pressed boards from Home Depot. I spray-painted them in crazy colors (I was DYING for some color that day -- I sort of regret it now.) and put them up with brackets above my book shelves. Doing this created five long shelves that are 12 inches apart and almost a foot deep. I purchased a bunch of plastic shoe-sized boxes and some really fun labels to store goodies. I got them for about $1/each. I stacked them two tall on the shelves (I actually only have one shelf filled with these and would like more). The shelves hold crafts and supplies of all sorts, stuff that is for sale on ebay, some videos and some mementos. I need to re-organize it!
The room itself has a good sized-closet and I FILLED it with plastic containters, some new some old. I spent more money on the containers in there than I did for all the shelves because I wanted some uniformity. I basically bought plastic filing cabinets on sale at K-Mart and combined them with every plastic storage thing I had ever purchased before displacing innumerable things in my bedroom closet and bathroom but I didn't care!
I have pictures of the craft closet somewhere. Once I clean up my office I'll post pictures if anyone would like to see it to get some ideas for their own space.
I'm very happy with it, overall!
