To accomplish this, I go for a walk. I live in a densely populated urban part of town, but there are still trees, waterways, and other places that I can look to find my answers. When I walk, I walk briskly, at least at first. I want to get my heart rate up, I want to get oxygen flowing more heavily to the brain, I want to engage my body and breathe deeply and feel very awake. As I walk, I scan around me, looking for some random set of shapes that can offer me an answer. Once I do, I stop for a few minutes, take a drink of my water, and slow to a nice leisurely pace while I gaze. Usually within seconds, an answer starts to form. After I get a few impressions, I stroll home slowly, giving myself ample time to mull on the meaning of what I saw. By the time I walk in my door, the divination is finished, and I can take my next action with confidence gained through the knowledge I earned.
Sometimes, I'll focus on objects that are specific to my query. If I am looking for answers that have to do with things of an airy nature, I will look to clouds or things blowing around for my pattern to scry. If I am looking for answers to an earth-oriented question, I'll look into trees and stones. I will sometimes just watch for a shape to jump out at me, from whereever it may, and will often use this technique when I don't have as much insight into a question to start with.
Just the other day, this was the case. I was stuck on a particular spell that I plan to work this evening. I couldn't find the right direction to go, wasn't sure on the best method to use, and really needed some guidance. I took a walk and a few blocks from my home found a nice leafy hedge. There were all sorts of animal shapes in the hedge, each telling me a different aspect of my situation that I needed to consider. Some thoughts popped into my head on a direction I needed to go with the spell, including exact colors that I should use for the working. Lastly, across the far side of the hedge, a symbol that I should use outlined in the leaves, practically outlined for me. I snapped a photo with my digital camera, printed it out, and outlined the shape, which I am now working on carving into a wooden talisman.
I go to that particular hedge often, because it's always offered a lot of sage wisdom. From time to time, I'll fill up a water bottle with water from my koi pond, and take it to the hedge as an offering. I find that if I discover a particular place in my wandering scrying practice that answers a lot of questions, that it's a very respectful gesture to the spirit of that area. Over time, that can help build a lasting relationship with the spirits around a scrying spot, and they can give you solid and clear answers time and again.
Hedges are but one place you can scry, but anyplace that offers a random pattern to gaze into is potentially useful This could be anything from a patch of grass to cracks in the pavement, anything you can see (or hear, feel, etc. Some people will scry with their ears, listening for random sounds. Others will feel something until they get an impression.)
