Wash the cucumbers, drain well, and place them in a large, non-reactive bowl (this means ceramic, enamel or glass as opposed to metal). Pour boiling water over the cucumbers to cover. Let stand at room temperature for 24 hours. (Placing a dinner plate on top will help keep the cucumbers fully submerged.) The next day, drain and rinse the cucumbers. Place the cucumbers back in the bowl, and repeat this step each day for the first 4 days.
On the fifth day, drain and rinse the cucumbers, and then cut into approximately ¼-inch coins. (I prefer my pickles on the thicker side; adjust thickness according to your preference; see notes.) Put them back into the bowl.
In a large pot (still on the fifth day), combine the vinegar, sugar, salt, and the wrapped spices. Bring the mixture to a boil, and then carefully pour over the cut cucumbers.
Let stand for 24 more hours. On the sixth day, drain the syrup and bring it to a boil. Pour over the cucumbers.
On the last day, drain the syrup again and bring to a boil. Add the cucumber slices and bring to the boiling point.
Pack into clean canning jars, leaving ¼ inch of headspace. Discard the bundle of spices. Process the jars for 10 minutes or store in the refrigerator.
