There are patterns designed specifically for tiles, but you don't have to be limited to just using tile patterns. If you find a stained-glass pattern, you can easily adapt it to the mosaic.
The main difference between mosaic patterns and stained glass patterns relates to the spacing between the glass pieces and the size of the individual pieces.
Many pieces of the mosaic are used outdoors. Due to the temperature range outside, mosaics made of large pieces of glass will crack over time. To avoid this, make sure that the glass is well fixed in the cement and that there are no air bubbles under the glass. If you want to buy glass art tools, online then you are in the right place.
Another factor to consider is the amount of space between the individual glass pieces. Depending on the pattern you're using, the distance between the glass pieces should not exceed 1/4 inch.
To convert a stained glass pattern into a mosaic pattern, you must first resize it to fit the size of your mosaic template. Next, cut the individual pieces of the 1/16th pattern into 1/8 smaller. This will give you a 1/8 to 1/4 inch gap. If you want the look of traditional stained glass, cut 1/16 of the individual pieces smaller. The spacing between adjacent glass pieces should be uniform.
If your chosen pattern has large pieces of glass, cut out these pattern pieces (the smallest 1/16 inch), then break this pattern piece into smaller pieces with 1/32 inch space between pieces. Using this smaller space within the design, where it used to be a large piece of glass, will move the unit and prevent future cracks.
By using the two different blanks, the overall effect will be a uniform piece. The larger spacing will provide definition and the smaller spacing will uniform the color.
If you are not using a clear template, place the sticky side of the clear contact paper up on top of the form. Continue as if you were using a transparent mold until all of the glass is on the contact paper (upside down). Then carefully place the glass contact paper into your mold.
