flat-packed frustration

What is it about flat-packed furniture that can turn a normally sane, rational, logical, reasonably intelligent person into a frustrated, raving, tearing her hair out, lunatic? Could it be the instruction sheet written by someone whose only knowledge of english is via an asian/english dictionary? Could it be the bits they fail to mention have a right or wrong way up until you have numerous other bits connected to them? Arrrghh! Two shelving units took about 2 hours and several glasses of wine. Perhaps it was the wine :]
What brought about this exercise in frustration you may ask. Well, for about the last 20 years my studio had been located in a converted garage, known affectionately as 'the garargio' (garage/studio). It's 9'6" x 18'6" with a fairly low ceiling and is absolutely crammed with stuff. My constant complaint has been that because it is separate from the house I am less inclined to go out there in the summer (because the house has air-conditioning) or in winter (because I have to go out in the cold/rain etc). Also, it meant leaving husband and kids inside when I wanted to sew (yes, I know this could be seen as an advantage). But time moves on and so do husbands and kids. Now with an ex and kids grown up, I've been thinking an inside studio, in the 2nd bedroom, would be much more enticing and conducive to creativity. I know its not all going to fit - 16sq mtrs into 10sq mtrs just doesn't go - but the fabric and some of the machines will and the garargio can still be used for storage. So the great studio relocation is underway. This has also necessitated the puter relocation from the 2nd bedroom into the dining room.
