I use a pair of garden gloves that are rubberized on the palm side and a loose knit on top. I tried the quilting gloves with the dots and they just didn't work for me. They didn't have enough grip and even in the large size the fingers were too short for my fingers.
I also use several tables pushed together at a right angle to have lots of support for the weight of the quilt.
I don't use the slider, but I do use a plastic cutting mat from Walmart (someone here posted about them awhile ago!) to cover the hole in my table. I just use painters tape to hold it down and so far it has worked well.
I am curious to see what others have to say.
