There is a new service offered by ScrappyDew and Michelle Belle Creations. Got an email on it and decided to check it out. Here is the link if you are interested. It is a pay for service for $20 annually that searches the Internet for sites that have free svg's. I don't have any association with the site, just passing it on for those interested.

Decided to go for the service and quickly received 2250 svg files...any by popular designers you know. It is updated monthly.
Here is a screen shot that lets you view and search for svg's. The link then takes you to the website of the designer to download the free svg.
