Google Cleft grafting.
There are fancier ways of making a graft but cleft grafting works 95% situations. I use cleft grafting for all my grafts. I have around 95% success with apples, 100% plums, pluots, pluerries, and apricots.
Peaches and nectarines were poor in past years about 10% but this year it was 100% (7/7). Wait to graft peaches and nectarines until temps reach above 75 optimal low 80s.
Practice making correct cuts on material you have pruned.
Start grafting after any frost has chance.
Try to get scion material that is similar diameter to your rootstock or where you are going to graft. Also the scion should be dormant in decidous fruit. sub tropical or tropical the scion should have swollen buds but the buds shouldn't have started actively growing.
Matching the cambium layer is essential to a successful graft. If the scion is too small that you are unable to match both sides of the scion to the rootstock then match only one side.
Wrap the graft in parafilm making sure that everything is covered (where the cut on the rootstock ends to the top of the scion).
Then secure the graft in the vynil/rubber tape (only where the rootstock and scion meet). Label the scion with date and variety.
After the graft check periodically for signs of growth and remove any growth below the graft. once the graft has taken and the graft has calloused (2-5 months) remove the vynil tape (rubber bands fall off on their own. Do not mess with the parafilm the buds will push through it just fine and will degrade by itself.
I would start grafting with plums or apples as these are really easy.
