I agree if you could do it in sections it will really help. I have never made one with denim yet but have made several rag quilts. I always use a 7 inch block and just a half an inch inseam even thou all of the patterns that I have seen say a 1 inch. So if you try another you might want to use a lighter fabric and maybe just use 1/2 in seam. Keep at it you can do it.
