The Studio 180 Design’s Tucker Trimmer is my power tool! I use it every time I’m working on a quilt. Here are just a few of the units you can make with the Tucker Trimmer. I used a charm pack – all the squares are 5″.
Half Square Triangles
Quarter Square Triangles or Hourglass units. Layer two half square triangles (untrimmed) right sides together, nesting the seams. Draw two lines each 1/4″ from the center diagonal. This line should be opposite from the previously stitched lines. Stitch on lines. Cut apart. Follow the captions on the pictures to spin the seams, creating less bulk in the center. Great tip and can be used when making many different units.
Looking at the Size chart above, you’ll see that when making quarter Square or combination units the 5″ charm square will make a cut size of 4″ and a finished size of 3 1/2″. Each of these units have a second seam so the units will be smaller. To trim the Quarter Square Triangle units place the full circle in the upper right (lefties upper left)’. Line up the common diagonal on one seam and the 4″ solid line on the other one. Those lines will intersect at the exact center of the block. Trim the first two sides, rotate the block, lining up the trimmed edges with the 4″ lines on the Tucker Trimmer. Trim sides 3 and 4 (second trim). Perfect Quarter Square Triangles every time!
Combination Units are made with a solid 5″ square and a half square triangle unit. Center the Half Square Triangle on top of the solid square , centering it. Draw the lines corner to corner on the HST – opposite direction of the seam. Stitch and cut apart. Press to the larger triangle by placing it on top on your pressing mat. Press with your iron, then finger press. Final pressing from the front before trimming. This will be trimmed to 4″ and finish at 3 1/2″.
When working with Charm Packs (5″ squares) I prefer to make my units smaller. The charm packs have pinked edges and are not perfect 5″ squares. I would make all my units cut size 3 1/2″ so they finish at 3″. You’ll be trimming off a little more fabric than usual. And 3″ squares are a common size in lots of quilt blocks! Do you like to work with Charm Packs?
The Square in a Square unit certainly looks easy enough – Just sew 4 triangles to a square. How hard could that be? Well – very. The center square is precision cut, and each triangle needs to be positioned perfectly to be sure the square is centered accurately. Ugh.
By making the precision cut easy and oversizing the triangles the Square in a Square can be made easily and accurately.
