when i do a trip around the world or even just a scrappy blocks ....i chain piece from top down row 1 to 2 then with out snipping the thread add row 3 and so on ...then i look it all over and make sure it is all in the right place ....press row 1 one way 2 the other etc ....i know this is the stage of the quilt i like to call swiss cheese .....then just fold and sew ......never clipping the chains ...saves time ...and if i mess something up .only have to take out 2 seams and if scrappy -never get two of the same color next to each other
