Can large letter stand by themselves? Will the top swing? Yes, all of our large letters are freestanding on even ground. For grass or uneven ground, we always suggest buyer install supports against back of letters to add stability. Using sand bags can help better. For top-heavy letters like F, P, 7,4, we also design the base plate to keep balance.
