TL;DR at the end. More details to explain my process:

I am using [this pattern](https://www.youtube.com/watch?v=geVWlxre3p4&list=PLC9rIzhRq7QPSsL9OhZLD9JfOq8SjOEaW&index=39). I have never done letters before but I got this idea for a sweater for my girlfriend (she studies seaweed) and I really want to give it a shot. In the pattern, you start with making a ribbed hem for the front panel, then put extended hdc into the horizontal side. When the person making the pattern did it, it turned out to be 2 ehdc per row in the hem. My girlfriend measured herself recently and her low hip is about 42" circumference. Divide that by two (half for the front panel of the sweater and half for the back panel) and I get 21. If I am putting two ehdc in each row of the hem, that gives me 42 ehdc to work with. I want a little buffer around the edges of the words so I made a grid 40 stitches wide.

She didn't measure the length of her torso so I had to guesstimate. She's much taller than me but it's mostly in the legs, so I figured I could measure my own torso and add a few extra inches. I don't have a measuring tape so I took a piece of yarn, measured from low hip to collar, and measured the length of that piece of yarn. I ended up with roughly 28". I did a little sample square and calculated that the ehdc are about 5/8" tall and I need 3 of them per inch. I ended up with 46 rows for the length of my grid.

I then made the pattern on the right with the letters. I'm working in Google Sheets so not the most sophisticated program. I made the cells square; maybe I should make them more like how the ehdc look?

TL;DR I've never crocheted letters before. I welcome any feedback from experienced folks to determine if this pattern will fit, if my measurements are accurate, or if I'm just completely off track before I start crocheting. Thank you!

First time crocheting words; will this pattern work or should I redo it?
