Proper pattern making is crucial to the beginning of any project; small or large. The procedure of making exact matching copies of assembly copy and pattern copy to the original drawing cannot be overstated. Pin the 5 layers of paper as shown below to a firm workboard. Firmly trace over the original design with a ball point pen, making sure you're making an impression on to the bottom oak tag layer. After completely tracing over the original drawing, lift one push pin checking to see that all lines from the original have been transferred to the bottom layer. Put the first pin back in place, and then do the same to each of the corners of the drawing, always putting the pins back in place before moving on to the next corner. When you're finished, cut the bottom layer and use it for your pattern pieces. The benefit of using oak tag for the pattern copy is that oak tag is stiffer and it won't distort when you're tracing around it. The middle layer will be the copy used for assembly. The top layer which was your original copy can now be stored away if you ever need to make the project again.

We have two markers for writing on glass; a black marker by Staedtler, and a white marker by Uchida called Deco Color.
The Staedtler black marker has an extra fine, hard point that won't get soft with use. It's called a permanent marker (not really) and is durable once used on glass, but it can be removed with kerosene.
The DecoColor white marker is a fine point paint marker (not as fine as the Staedtler marker) that's great for writing on dark glass. It too can be removed with kerosene.
Both markers should be capped when not in use as they can dry out if not capped.

This 18" straight edge is great for cutting straight lines on glass as it features a non-skid rubber backing. The ruler also has a substantial thickness so your cutter won't ride up on the ruler as you're scoring your glass. The ruler is marked on one side in 1/16" divisions and the other side with 1/8" divisions. An essential tool for any glass artisan.

L-squares are used for making perpendicular scores on glass. There's a ridge on either side of the L-square (for both righties and lefties) that gets placed on an edge of the glass. You can then use the square as a guide for your glass cutter to make a perpendicular cut to the side of the glass that the ridge is resting against. You can also use the square for drawing perpendicular lines as you draw your patterns. Available in 12" and 18" lengths.
