How to get heaps of ashes

OK, so, if you have the Soot Sack to carry ashes in for the guy in the Glass Workshop on route 131, there is a much easier way to get ashes rather then running around, finding all of these pokemon (like Spinda) that you already have or don't want and then waiting for ages while the grass turns grey again. What you could do though, is get a couple of Repels (any Repel will do, I use Max Repel because you don't have to use that many), run around in the grass until all of the grass has turned green, then go to the glass workshop and talk to the guy there who will ask you what you would like him to make for you.

Choose what you want and if you want an item that you don't have enough ashes for then go outside and CHECK IT OUT! The grass should all be grey again and if you use up your Repel, just use it again and just keep running around the grass and going to the Glass Workshop until you get enough ashes for your dream item or you just get bored.

Hope it works! It did for me.
