Hi "Rookie",  🙂

I agree with what Jafar said.  The next time that you do a wedge-graft, try to make the depth of the split and the length of the wedge about equivalent.  That being said, the graft looks really good in terms of the callusing between scion and rootstock.  It should do really well!  As for "appearances"...  believe me I've made more than my share of ugly grafts over the years.  Sometimes it just can't be helped, especially in cases where the diameters of root and scion aren't closely matched.  The main thing to remember is that a successful graft is a good graft!

that's a lot better than some of my early grafting attempts!  I don't have anything else to add, but wanted to encourage you.  With experience you will keep getting better and better.  I did.

Greg,

I have perhaps a half-dozen apple grafts that still look a bit like that (--although I usually use a whip-and-tongue graft on apples--).  Your graft looks great!  I don't mean to be a poet, but, year-by-year those "nubs" disappear.  With a strong, healthy graft, the plants can be very forgiving of "looks."  What's important is a strong a priori compatibility of the varieties used, and a strong union of physical strength and vasculature.  

Jeez!  I make it sound so intimidating!  ....  You're graft is great!  With this success, feel free to continue your grafting and adding to your orchard of whatever size.  Just one successful graft and you know you can do it!
