MS Word is such a time saver when it comes to lettering. In the olden days, the process involved a trip to the print shop to enlarge the font and then tracing it backwards against the window onto the fusible web. Now I simply go into Word, select a font and manually type the size I want in the box. The drop down menu for the font size usually goes up as high as 72 but just ignore that and type in a larger number if you require larger print. Circled below you will see that I am using Harrington font in 175 point. My large format printer takes sheets 11 x 17, so choosing a landscape orientation with narrow margins yields pretty much the exact size I want for my 20-1/4" antependiums. After typing my word, I click the arrow to the right of the blue A to give the menu for text effects. Choosing "outline" gives hollow letters, thus saving ink.
When I am ready to print, I click on "printer properties" and under the advanced setting I can choose to print my letters in mirror image. This means I can trace directly onto the paper side of my fusible web and not have my letters come out reversed. I iron this web to the wrong side of my fabric, cut out the letters and fuse them in place on my fabric.
