Yesterday at my P & Q group we had a lesson on one method of quilt as you go ( or joining pre quilted blocks ).
- All the blocks you wish to join must be quilted through top, batting and backing fabric.
- All blocks need to be the same size.
- Each block needs to be sewn around the outer edge as close as you can. ( trim all excess )
2 sizes of joining strip need to be cut. ( can be same fabric or 2 different )
- Top strip 1 1/4 " wide ( and the length of the blocks )
- Back joining strip 2" wide and length of block. Fold this in half right side out and iron.
- if the order and direction of the blocks matters, lay them in place, right side up and number them.
- Pin then sew the back joining strip ( the folded one ) to the right hand side of the back of block one. Raw edge to raw edge. (see pic ) make the seam just less than the usual 1/4".
- turn this block and now sew the narrower strip down the same hem line ( on the other side )this time making the sewing line slightly wider than the usual 1/4". ( this stitching line should cover the first line of stitching. ( check )
- place block 1 and 2 right sides together and pin the unsewn edge of the narrow strip to the left hand edge of block 2.
- Turn both blocks to the back side and pin; then hand sew down the folded edge of the joining strip.
- Using the same sequence continue sewing your blocks together, till you have the desired number in a row. Then another row etc.
- Now using the same method join 2 finished rows together horizontally. Just like you do if you are joining blocks with sashing.
If you have the fabric available cut the joining strip in a long length and cut off after each seam, less wastage and they are then all the correct length. You can even use a string piecing system once you have sorted the method out.
