This is from Tatting, A Potpourri of Patterns. It is 5 individual triangle motifs joined together. I made it in size 100 which taxed my eyes a bit but I love the delicate lacy-ness of it. The pattern required different lengths of bare thread depending on if you are working on a side or corner. I did the best I could considering I didn't use any kind of guage.
Here is an individual motif. I thought about pressing it before taking a photo, but with something that small I'd probably just burn myself so I flattened it against the table and hoped for the best.
This pattern is also a part of my resolution project.
