24 x 28 huh Well.....if you pace yourself I am going to throw out a guess of six months.
Of course.....not to be a downer....but.....what will probably happen is that you already have enough stuff to fill it but won't realize it until you start unpacking
You're probably right especially once I go through all the things I haven't unpacked since I moved from my old house. Maybe that will be enough to slow me down on buying new supplies until I use up some of the old ones. Who am I kidding, not gonna happen.
If nothing else, it will give me the room to spread out all my different crafts so that I can actually do any one of them without having to make room. What's been happening lately is that I will think about doing x,y, or z craft and decide not to because it would be too much hassle to make the space for it or I can't even get to the supplies because they're packed up behind something else. Only sewing is getting done now.
