I have a few more pictures of
how I graft here...
Other materials I use... I've used string, self-adhesive coban, humidity bottles (water bottles, pepsi, etc.)
What I prefer to use... parafilm and two razor blades. If I have those two items I can generally get 97.5% of my seedlings 2 weeks of age to take and up to 100% is not unheard of. However, if I can be honest, 980 successful seedling grafts out of 1000 grafts is a perfectly acceptable loss in my opinion when dealing with grafts this small and I honestly feel like anyone using my parafilm style grafting can get those types of results with just a few months practice at most.
Parafilm stretches when pulls slowly.
Parafilm rips when pulled fast.
Parafilm sticks to itself.
Parafilm keeps your seedling firmly in place so it does not float off your grafting stock.
Parafilm seals in humidity and prevents drying out of the graft thus promoting the healing of even very tiny grafts without the need to concern oneself with humidity.
With those things in mind, you need only pull two 1 inch /(2.54 cm) pieces for most small seedling grafts 2-4 weeks of age.
The first piece of parafilm you tear in half lengthwise fast. This will give you a half inch strip of parafilm to use to wrap the base of your stock Pereskiopsis or Trichocereus for example. Alternately, you can also buy parafilm in 0.5 inch rolls and forego learning to tear parafilm properly. It is a skill that is only needed if you don't want to purchase two rolls of parafilm.
Your then simply cut through your stock plant at the midpoint of the parafilm you have wrapped around it.
Place your scion off center after first cutting a 1/3 to 1/2 of your 2-4 week old seedling off. The top portion should be lightly wrapped with your 1 inch piece of parafilm. This parafilm should have been stretched thin however prior to the draping. The corners of the parafilm are brought down slowly to ensure the seedling does not tilt as this can adversely affect the ability of the seedling to take. A slight twist when your done and or a scrunching motion where the top wrap meets the wrap around the stock should tighten things up a bit.
Do not remove the parafilm ever... The graft will do this for you as the scion grows through the parafilm.
