devoted to the study of temari and mathematics
This investigation looks at a specific type of obi based pattern known as a thimble ring. These designs are actually patterns from another Japanese craft (thimble rings) applied to temari. There are a few designs in the Japanese book known as Cosmo 3 (ISBN 4-8377-0281-3). A good source of information is the Japanese website known as Thimble Japan.
All thimble ring designs are done on simple divisions. The higher the division, the smaller the sections of the design will be. I found that even if I wanted to use fewer sections (like 8), it is useful to do more divisions to help keep the base lines straight and to keep the spacing of the stitches even. I like to start with an S16. A thin, flat marking thread will give the best result unless you are doing a special effect like the first variation below.
I do not mark the obi when I am doing a thimble ring. I place the pins and then measure up and down from them to establish the width of the band. One sixth of the total circumference of the mari is a nice width but you can choose whatever looks good to you. If you get too wide you will not have complete covereage about the obi area. In the picture the red pin is the N pole, the black is the S pole and the white pins show where the obi would be.
Place support lines for the top and bottom of the band. This thread can be the same weight as your design threads. It is often nice to use one of your design colors or a mari matching thread in case it ends up peeking through when you are all finished. These lines should be firmly anchored and not loose or they will be easy to pull out of place with your stitching.
The basic stitch pattern for thimble rings is a zig zag from the top line to the bottom continuing aroung the ball back to the starting place. Subsequent rounds can be placed to the right or left of the initial zig zag (or both right and left) with the direction being shown by small arrows next to the lines in the diagram.
Other designs may use more than one zig zag, or may have the zig zag cross multiple marking lines.



There are three possible ways to make the stitches for the thimble ring. They all have their own strengths and weaknesses as well as best applications.



This a a fairly basic design done with two alternating zig zags. They both progress to the right as it is stitched. This one was done on a Simple 8 division. It is notebook entry #060902.
This design is done by wrapping the base wraps in a layer before stitching the thimble ring. Then the thimble ring is stitch with the colors matching the wraps. The stitches are spaced apart giving an open look to the design. It is notebook entry #060901.
This design has a super wide thimble ring. The extra width causes the center portion of the design to be open like the second variation while the upper portions are densly packed like the first variation. It is notebook entry #061101.
This design uses the same stitch pattern as the previous ones but in this case the colors are blocked. One zig zag is always stitched with red and the other is always stitched with yellow giving a very different look from the previous ones. Additionally, this one was stitched with three rows on each zig zag before alternating causeing a more jagged line where the colors come together. You can see clearly on this one how my tension was not consistent, causing the edges of the thimble ring to be rougher than they should be. It is notebook entry #061001.
This one was done with perle #8 and once again, the troubles with stitch tension are evident by examining the edge of the thimble ring. A smaller thread seems to make the tension problem even more critical. There are more sections to this design because the zig zags go across more than one division line. In this case one line is skipped and multiple zig zags are used to fill in. It is also done on a simple 12 division. It is notebook entry #061002.
This one is done on a simple 16 division giving smaller sections. Also, the thimble ring itself is much narrower than is usually done as a stand alone pattern. It becomes more of an obi embellishment than a design in its own right. The effect of the interlocked blue and tan bands on a field of red is done with careful color placement. There is one set of opposite zig zags. Both are stitched with red for half of the distance and then one is stitched with blue and the other with tan to finish up. It is notebook entry #070201.
The variations shown here only scratch the surface of what can be done with thimble ring designs. For the most part these were done with one simple type of zig zag and only one direction of stitching. By varying the color placement, zig zag size, number of zig zags, and direction of stitching there are many more designs to explore. Thimble rings can be wide enough and complex enough to be the main focal point of the design or they can be a wonderful complement to a simple division temari.
