TUBE WRITING AND LETTERING : Page 233
As far as technique is concerned, we feel that almost any style of lettering can be mastered by the studentwith moderate practice.
The student might begin with the following method: Lay a piece of waxed paper over any of the examplesof lettering illustrated on these pages. Then using acone with the proper sized tube, the letters beneaththe waxed paper may be used as guides. Some styles 'such as the Old English will require two tube sizes forthe thick and thin lines, while the Free Script and Modern Block styles may be rendered with a singletube size. After you are satisfied with your proficiency,the wax paper may be abandoned and you are readyto work directly on the cake.
