I had built a table that had support to the left and depth to do my quilting. NEVER did that over the shoulder routine that back in the 'old" days was always recommenced. Find anything such as an ironing board, table or TV trays that can help support the weight of the quilt. I read an article of one lady who had a large table and she stood up doing her machine quilting. Try to start on a small project and then work up to the larger size. Good luck !!
