For these quilted marine-themed table mats, we used the embroidery designs from the One-Color Fishing Boat Set for the large (5" x 7") hoop.
The finished size of a mat is about 18" x 25".
Besides embroidery thread (either polyester or rayon), you will need
Embroidery
Stabilize white fabric with light-weight cut-away stabilizer and embroider the ship designs for the large hoop. For each table mat you'll need 3 stitch-outs.
Trim the stitch-outs to 6 1/2" x 7 1/2" rectangles.
Cutting:
For each mat, out of white fabric cut
The Block:
Position a 2 1/4" aqua square on one corner of a white 4" x 4" square.
Draw a diagonal and stitch on the line. Cut off the corner, trimming seam allowance to 1/4", unfold and press.
Repeat for all the corners of the white square. Make 10 squares with aqua corners in this way.
Cut the 3" x 3" blue squares along the diagonal to make 40 triangles. Sew each triangle to the sides of the white-aqua squares one by one.
Unfold and press after each seam. Trim the "ears".
Assembly of the Top:
Sew 3 rectangles with embroidery into a strip measuring 6 1/2" x 21 1/2".
Sew the 2 1/2" x 6 1/2" strips to the ends of the long strip.
The final strip will be 6 1/2" x 25 1/2". Press the seams. This will be the central part of the mat.
Sew the 1 1/2" x 25 1/2" blue strips to the upper and lower edges of the embroidered strip.
Sew the blue-aqua-white blocks into two strips, 5 blocks in each strip.
Sew the strips to the upper and lower edges of the central part.
Quilting and Finishing:
Now place the backing on a flat surface (table) face down. Cover with batting. Spread your working piece over it.
Pin all three layers together with 1" pins and start quilting. We in a free-motion style all over the mat.
After the quilting is finished, press the work with heavy steam and square the work -- all corners should be 90 degrees and opposite sides should be of the same length.
Top-stitch ric-rac tape over the seams between the central and the border parts (optional).
Finish the raw edges with the binding.
Your mat is ready.
Enjoy!
