How big are the cloth swatches you're talking about?
Unless you have specific requirements that your current lens cannot meet, I'd suggest you try using it. You might find it's all you need. Sure a 50mm prime has a larger aperture (good for low lighting situations and more), and better image quality (how much do you really need?), but until you know what you need, there's no point buying new gear.
For Canon, the EFS 18-55 allows a bigger magnification ratio (althou still < 1) than the 50mm F1.8, Since it can have longer focal length 55mm and shorter MFD. So in this aspect it might be more suitable if close up of the fabric is required. The IS might be useful also.
Also, it have wide end 18mm for full body portraits and this can be quite useful if the situations arises.
