hun, if you will go to bernat.com and take a look at the different yarns they offer you will be able to see the difference for yourself, of for a better example, get hands on and go to a yarn store or craft store, or even walmart.

simple would be such as red hard worted weight.

filiment would be all the little bobble and texture threads that you add to yarn your working with for effect. They can’t stand on there own because they don’t have enough body to do so.

natural crimp would be the bernat light and lofty that I am using to make a ponco with for this winter. it is expencive but beautiful. it is wavy and looks homespun.

laces would be the thread i believe but i cant swear to that one

again, go to a yarn store and get some hands on info.

Simple yarn is that which is made from a single fiber source such as cotton, wool, mohair, acrylic and is smooth to the touch and look.

Complex yarn has different fiber sources in it, sometimes two different fibers are plied together, it can be Indian plied, braided, or be loopy like terry or boucle.

Filament yarn is like made from a single stranding of something like silk which is pulled from the cocoons in one long strand.

Natural crimp refers to wool and mohair. It is the little wavy look of each fiber. The tighter and smaller the crimp the finer the fiber.

Laces I have no idea.

You may be able to find some of the pictures of these on http://www.interweavepress.com in either the Handwoven or the Spin Off magazines.

The internet is very helpful — you can find ANYTHING you can think of. But you need to do some work for it.

A filament yarn is a yarn of a synthetic, fibre-forming, polymeric material comprising a plurality of filaments having a substantially rectangular cross-section and having a birefringence asymmetry across the width of the filaments, each of the filaments being twisted about the longitudinal axis of the filament in such a manner that the overall lateral dimension of the twisted filament corresponds substantially with the length of the rectangular cross-section of the filament. In other words, it’s a long continuous strand of synthetic material. Reeled silk is the only natural filament yarn. Synthetics are formed in these very long strands, are then cut up into smaller pieces, some are crimped to resemble wool, and then are spun into yarn. If you remember Phentex, it was long continuous strands bundled together to make yarn … not pleasant to touch or work with.

Crimp is the wavy structure of wools. Most sheep have crimp, although there are some that have very little. Crimp is what makes it easy to spin and hold the fibres together into a yarn. Merino, the finest wool, has the most crimp, and mohair usually has almost none. Alpaca and llama also have little crimp. It takes a lot more twist to make them into yarns.

Lace is an openwork fabric, patterned with open holes in the work, made by machine or by hand. The holes can be formed via removal of threads or cloth from a previously woven fabric, but more often open spaces are created as part of the creation of the fabric. There are many types of lace, defined by how they are made.
