I am not a huge crafter, but I do occasionally scour my local Dollar Tree to look for smaller DIY projects. My most recent (successful) find was $1 Certificate of Achievement frames. I purchased five of these for an upcoming bridal shower. These are the larger frame fit for certificates.
Next I bought a few of these from Michael's Craft Store for $6.46 each. Testors CreateFX in Gold. They are small so you might need to purchase more than one for a larger job.
Pop out the back of the frame, lay newspaper out (preferably outside), then have at it! I did have to use a few coats to make the glitter thick.
Once the frames are dry, insert your sign or picture and enjoy! If you are going to use the frames for outdoors I would suggest using a sealant. For more dollar store deals follow Table 1 Events on Pinterest at www.pinterest.com/table1events
