Hawaiian quilt pt. 1

Quilt design plan

I started a quilt. The idea for this quilt has been floating around my head for a few years. I had some Hawaiian printed cottons left over from other projects and I wanted to use them in a modern style quilt. I have only three colors to work with, purple, green, and white. I had a hard time visualizing the overall look of the quilt, so I drew up a version using Inkscape*. I could have taken this a step further and scanned the fabric into the drawing, but this was close enough. I still have not decided on the final borders. It partially depends on how much of each color I have left after piecing the blocks. I'm fairly certain I will not be using green on the outside border. I may go for white instead with green bias binding.

Here are the actual fabrics, cut and ready to go.

 

The pattern came from Fat Quarter Fun by Karen Snyder and is called Summer Fun. I really liked this quilting book. Most of the patterns are simple, using primarily fat quarters for the tops. This particular quilt is a bit small, IMO, so I've added some additional blocks to bump it up to a full size. I'm also using yardage instead of fat quarters. Because of that, I think I should have cut and sewn things a little bit differently. More on that later. I'm excited to finally have started this project.

*Inkscape has some nifty drawing tools, including cloning. I did not use that feature here, but it would have been a perfect opportunity to use it.

Singer Hemstitcher 72w-19 thread breakage solutions

Singer Hemstitcher 72w-19Hemstitching woes continue to plague me. Thread breakage with the left needle thread continues to be a persistent problem. The breakage is preceded by skipped stitches that cause the thread to wrap around the pierces where the piercers or needles eventually cut the thread. I have run through various scenarios trying to diagnose the problem. The timing of a machine is absolutely critical or no stitches form. In the case of a hemstitcher, the timing is a bit more complex. The position of the needles relative to the piercers and how they move as the fabric moves under the foot is all a part of the timing. A Singer hemstitcher 72w-19 has two bobbins which must be separately adjusted to work in time with the needles as they descend with the piercer. For a while I have thought there was a timing issue with the left needle.

Or maybe not. I have set and checked the timing and it appears to be right on. I have adjusted nearly every possible adjustable part. Even the pitmans that control the needle position and angle - something I dreaded touching. I adjusted the check springs. I have spent countless hours making one fine adjustment after another, studying the manual over and over. I feel as though I have hit a brick wall. It is rather frustrating to be stitching a customers blanket and have the left needle thread break every 5-12" for no apparent reason.

Check Tension


So off to browse the net to try and find some kind of solution. American and Efird is probably one of the best technical websites for manufacturers. They have an excellent article on thread breakage that has given me some insight. A checklist of things that might be causing some of the problems. One thing that I had observed the last mechanic to work on this machine do was wrench down on the tension discs. I have maintained tight tensions ever since. Tonight I loosened the tensions until the bobbin tensions took over than edged back to a balanced stitch. The stitch is better and perhaps that will solve some of the problems.

Needle Orientation


The next step was to look at the orientation of the needles, in particular the rotation of the needle in the needle clamp. Most every blog entry I have read says to turn the needle out to help avoid thread breakage. I think that is the wrong approach because it affects how the hook interacts with the needle. The needles should be aligned with the eyes opposite each other in a straight line. This may not make a lot of sense if you are not familiar with the machine, but mechanically, it does.

In any event, I still must plug away at stitching some customer orders with my fingers crossed that I will have fewer problems. If you are having stitching problems because of skipped stitches or thread breakage, I highly recommend the American and Efird article.

Oh and did I mention I had to fix the belt. Leather belts have a tendency to wear out. I used my last clip, so I must order some more just in case. I have extra belting because my machine can be used as either a treadle or with a motor. I don't have the fancy tool that punches a hole in the belt and compresses the clip. I learned a neat trick of using a drill to create a hole for the clip. It worked great.

Warning - Taggies Blankets have a patent


You probably have seen them. These blankets are made of two squares of fabric with ribbon loops sandwiched around the edge. I have seen them sold on Ebay, online web sites and demonstrated in blogs and mommy discussion groups. Some well intentioned new designer could find themselves in a heap of trouble if they attempt to sell a similar product.

This is the kind of patent I dislike. The product is so simple. There is nothing unique to the concept other than the brand name. It is easy to copy and reproduce. It would be easy to unintentionally copy the concept. Just attach a ribbon loop to a product, and oops - patent infringement. (This particular patent extends to related products and not just the blankets, and would, of course, have to be tested in a court of law).

This is how the designer intends to treat potential customers and fellow designers. The designer states:
In our appreciation of your notification of any product infringements that you may find, a donation of TAGGIES will be made to a charity. In addition, your first name and state of origin only will appear on our Random Acts of Kindness page as sincere recognition of your efforts.
I think there are better ways to protect your product. Try superior product quality, customer service, shopping experience. Sure, others will copy and imitate, but you can do better in all of those areas. Build loyalty on trust - not threatened action.

Patent protection is only as valuable as the intended enforcement of the patent owner. This designer is actively protecting her patent and products. (They claim copyright protection too, although that claim is rather dubious IMO). Anyway, just a warning to any other designers - stay away from the "Taggies" concept.
