Where to get spacers for framing autographs

[Jakeman]

Hello, I was wondering if anyone here on Fanmail.biz who frames their autographs knows a good place to get quality spacer to put in frames so that the autographed photo being framed doesn't directly touch the glass of the frame. I'm aware a simple google search turns up tons of websites that sell them but I'm mainly hoping someone has experience ordering from a specific site who can vouch that they have good customer service and products. I also have checked local stores who offer framing services such as Hobby Lobby and Michael's but they all say they only offer spacers for custom framing orders which cost a fortune. I really want spacers as I find mattes to be unattractive, at least for the specific autographs I want framed. Any replies with advice or help of any kind would be very much appreciated, thanks!
